  Abnormal metabotropic glutamate receptor (mGluR) activity could cause brain disorders; however, its regulation has not yet been fully understood. Here, we report that protein kinase N1 (PKN1), a protein kinase expressed predominantly in neurons in the brain, normalizes group 1 mGluR function by upregulating a neuronal glutamate transporter, excitatory amino acid transporter 3 (EAAT3), and supports silent synapse activation. Knocking out PKN1a, the dominant PKN1 subtype in the brain, unmasked abnormal input-nonspecific mGluR-dependent long-term depression (mGluR-LTD) and AMPA receptor (AMPAR) silencing in the developing hippocampus. mGluR-LTD was mimicked by inhibiting glutamate transporters in wild-type mice. Knocking out PKN1a decreased hippocampal EAAT3 expression and PKN1 inhibition reduced glutamate uptake through EAAT3. Also, synaptic transmission was immature; there were more silent synapses and fewer spines with shorter postsynaptic densities in PKN1a knockout mice than in wild-type mice. Thus, PKN1 plays a critical role in regulation of synaptic maturation by upregulating EAAT3 expression.

• Mutational analysis of the regulatory mechanism of PKN: the regulatory region of PKN contains an arachidonic acid-sensitive autoinhibitory domain.

  C Yoshinaga, H Mukai, M Toshimori, M Miyamoto, Y Ono

  PKN is a fatty acid- and Rho GTPase-activated protein kinase whose catalytic domain in the carboxyl terminus is homologous to those of protein kinase C (PKC) family members. The amino terminal region of PKN is suggested to function as a regulatory domain, since tryptic cleavage or the binding of Rho GTPase to this region results in protein kinase activation of PKN. The structural basis for the regulation of PKN was investigated by analyzing the activity of a series of deletion/site-directed mutants expressed in insect cells. The amino-terminally truncated form of PKN (residue 455-942) showed low basal activity similar to that of the wild-type enzyme, and was arachidonic acid-dependent. However, further deletion (residue 511-942) resulted in a marked increase in the basal activity and a decrease in the arachidonic acid dependency. A (His)(6)-tagged protein comprising residues 455-511 of PKN (designated His-Ialpha) inhibited the kinase activity of the catalytic fragment of PKN in a concentration-dependent manner in competition with substrate (K(i) = 0.6+/-0.2 microM). His-Ialpha also inhibited the activity of the catalytic fragment of PRK2, an isoform of PKN, but had no inhibitory effect on protein kinase A or protein kinase Cdelta. The IC(50) value obtained in the presence of 40 microM arachidonic acid was two orders of magnitude greater than that in the absence of the modifier. These results indicate that this protein fragment functions as a specific inhibitor of PKN and PRK2, and that arachidonic acid relieves the catalytic activity of wild-type PKN from autoinhibition by residues 455-511 of PKN. Autophosphorylation of wild-type PKN increased the protein kinase activity, however, substitution of Thr64, Ser374, or Thr531 in the regulatory region of PKN with alanine, abolished this effect. Substitution of Thr774 in the activation loop of the catalytic domain of PKN with alanine completely abolished the protein kinase activity. These results suggest that these phosphorylation sites are also important in the regulation of the PKN kinase activity. Potential differences in the mechanism of activation between the catalytic regions of PKN and PRK2 are also discussed.

• Characterization of a novel giant scaffolding protein, CG-NAP, that anchors multiple signaling enzymes to centrosome and the golgi apparatus.

  M Takahashi, H Shibata, M Shimakawa, M Miyamoto, H Mukai, Y Ono

  A novel 450-kDa coiled-coil protein, CG-NAP (centrosome and Golgi localized PKN-associated protein), was identified as a protein that interacted with the regulatory region of the protein kinase PKN, having a catalytic domain homologous to that of protein kinase C. CG-NAP contains two sets of putative RII (regulatory subunit of protein kinase A)-binding motif. Indeed, CG-NAP tightly bound to RIIalpha in HeLa cells. Furthermore, CG-NAP was coimmunoprecipitated with the catalytic subunit of protein phosphatase 2A (PP2A), when one of the B subunit of PP2A (PR130) was exogenously expressed in COS7 cells. CG-NAP also interacted with the catalytic subunit of protein phosphatase 1 in HeLa cells. Immunofluorescence analysis of HeLa cells revealed that CG-NAP was localized to centrosome throughout the cell cycle, the midbody at telophase, and the Golgi apparatus at interphase, where a certain population of PKN and RIIalpha were found to be accumulated. These data indicate that CG-NAP serves as a novel scaffolding protein that assembles several protein kinases and phosphatases on centrosome and the Golgi apparatus, where physiological events, such as cell cycle progression and intracellular membrane traffic, may be regulated by phosphorylation state of specific protein substrates.

• Proteolytic activation of PKN by caspase-3 or related protease during apoptosis.

  M Takahashi, H Mukai, M Toshimori, M Miyamoto, Y Ono

  PKN, a fatty acid- and Rho-activated serine/threonine kinase having a catalytic domain highly homologous to protein kinase C (PKC), was cleaved at specific sites in apoptotic Jurkat and U937 cells on Fas ligation and treatment with staurosporin or etoposide, respectively. The cleavage of PKN occurred with a time course similar to that of PKCdelta, a known caspase substrate. This proteolysis was inhibited by a caspase inhibitor, acetyl-Asp-Glu-Val-Asp-aldehyde. The cleavage fragments were generated in vitro from PKN by treatment with recombinant caspase-3. Site-directed mutagenesis of specific aspartate residues prevented the appearance of these fragments. These results indicate that PKN is cleaved by caspase-3 or related protease during apoptosis. The major proteolysis took place between the amino-terminal regulatory domain and the carboxyl-terminal catalytic domain, and it generated a constitutively active kinase fragment. The cleavage of PKN may contribute to signal transduction, eventually leading to apoptosis.

• res2+, a new member of the cdc10+/SWI4 family, controls the 'start' of mitotic and meiotic cycles in fission yeast.

  M Miyamoto, K Tanaka, H Okayama

  In the fission yeast Schizosaccharomyces pombe, the cdc10+ and res1+ genes play a crucial role in the start of mitotic and meiotic cycles. They encode structurally related transcriptional complex proteins and regulate some S phase-specific genes. Here we report the identification of a new member of this family named as res2+. res2+ has been isolated as a multicopy suppressor of a res1- null mutant and specifies a 73 kDa protein, which has two copies of the Swi/ankyrin motif and shares the highest sequence and structure similarity with the Res1 protein. res2+ is largely redundant in function with res1+ and is required for the initiation of mitotic and premeiotic DNA synthesis, but has an additional role in meiotic division. Unlike res1+, res2+ is highly induced during conjugation and strongly depends on cdc10+ for its activity. We conclude that the fission yeast contains two functionally overlapping parallel 'start' systems, Res1-Cdc10 and Res2-Cdc10, the former of which plays a major role in mitotic cycle whereas the latter in meiotic cycle.

• Molecular cloning of a novel cytokine cDNA encoding the ninth member of the fibroblast growth factor family, which has a unique secretion property.

  M Miyamoto, K Naruo, C Seko, S Matsumoto, T Kondo, T Kurokawa

  Glia-activating factor (GAF) is a novel heparin-binding growth factor purified from the culture supernatant of a human glioma cell line. It shows a spectrum of activity slightly different from those of other known growth factors. We have isolated the cDNA which encodes human GAF. A homology search revealed that GAF would be the ninth member of the FGF family, and we therefore call it FGF-9. The human FGF-9 cDNA cloned by using oligonucleotide probes encoded a polypeptide consisting of 208 amino acids. Sequence similarity to other members of the FGF family was estimated to be around 30%. Two cysteine residues and other consensus sequences in family members were also well conserved in the FGF-9 sequence. FGF-9 was found to have no typical signal sequence in its N terminus like those in acidic FGF and basic FGF. Acidic FGF and basic FGF are known not to be secreted from cells in a conventional manner. However, FGF-9 was found to be secreted from cells after synthesis despite its lack of a typical signal sequence. It could be detected exclusively in the culture medium of cDNA-transfected COS cells. The amino acid sequence of proteins purified from culture supernatant of the CHO cell line, which was cDNA transfected and selected as a high producer of FGF-9, showed that no peptides were cleaved from the N terminus except the initiation methionine. The rat FGF-9 cDNA was also cloned, and the structural analysis indicated that the PGF-9 gene is highly conserved. Expression of the FGF-9 gene could be detected in the brain and kidney of the adult rat. Restricted gene expression in organs and the unique secretion nature of the protein suggest that FGF-9 plays a physiological role which differs from those of well-characterized acidic FGF and basic FGF.

• Absence of the type I IFN system in EC cells: transcriptional activator (IRF-1) and repressor (IRF-2) genes are developmentally regulated.

  H Harada, K Willison, J Sakakibara, M Miyamoto, T Fujita, T Taniguchi

  Interferons (IFNs) are a heterogeneous family of cytokines that exhibits multiple biological activities. Upon viral infection, expression of type I IFNs (i.e., IFN-alpha and IFN-beta) is induced in a variety of differentiated cells but not in cells of embryonal origin. IRF-1 and IRF-2, which bind to the same cis-elements within the promoters of type I IFN and IFN-inducible MHC class I genes, were identified previously. Here we demonstrate that the expression of both IRF and IFN genes is developmentally regulated in mouse EC cells; these genes become functional only after cell differentiation. Furthermore, cDNA-directed IRF-1 produced in undifferentiated but not differentiated EC cells efficiently activates the transfected IFN-alpha and IFN-beta and endogenous IFN-alpha genes, whereas IRF-2 represses the IRF-1 effects. These findings emphasize the dual function of the IRF-responsive cis-elements as positive and negative regulators, since they can be occupied by transcriptionally active or inactive IRF molecules. This type of regulatory mechanism might operate in other cytokine systems.

• Structurally similar but functionally distinct factors, IRF-1 and IRF-2, bind to the same regulatory elements of IFN and IFN-inducible genes.

  H Harada, T Fujita, M Miyamoto, Y Kimura, M Maruyama, A Furia, T Miyata, T Taniguchi

  Viral infections commonly induce expression of type I interferon (IFN) genes. The induction is transient and involves transcriptional activation wherein a positive factor, IRF-1, binds to upstream regulatory cis elements. In the present study we report the isolation of a cDNA encoding a novel factor, termed IRF-2, that interacts with the same nucleotide sequence elements as IRF-1. Both genes are inducible not only by virus but also by IFN. Unlike IRF-1, IRF-2 does not function as an activator; rather, it suppresses the function of IRF-1 under certain circumstances. Our results suggest that transcription of the IFN and IFN-inducible genes is regulated by two similar trans-acting factors that apparently compete for the same cis-acting recognition sequences, but which have opposite effects.

• Involvement of a cis-element that binds an H2TF-1/NF kappa B like factor(s) in the virus-induced interferon-beta gene expression.

  T Fujita, M Miyamoto, Y Kimura, J Hammer, T Taniguchi

  Interferon-beta (IFN-beta) gene is transcriptionally activated following virus infection of various cell types such as fibroblasts. In the previous studies, regulatory DNA sequences that mediate the virus-induced transcriptional activation have been identified within the 5'-flanking region (up to around -117 respect to the CAP site) of the human IFN-beta gene. The sequences contain binding sites (-100 to -61) for a transcriptional activator, IRF-1, the gene of which is also virus-inducible. In the present study, we focused on an additional cis-element, located between the IRF-1 binding sites and TATA box. Interestingly, the element coincides with the previously identified elements for the transcription factors H2TF-1 and NF kappa B. The element, when tandemly repeated, functions in activating the distal gene expression in either constitutive or virus-inducible manner depending on the cell type. The results suggest the importance of cooperation between IRF-1 and H2TF-1/NF kappa B-like factor in the maximal IFN-beta gene induction.

• Induction of endogenous IFN-alpha and IFN-beta genes by a regulatory transcription factor, IRF-1.

  T Fujita, Y Kimura, M Miyamoto, E L Barsoumian, T Taniguchi

  Interferons (IFNs) have an important role in cell growth and differentiation. The most well-known function of IFNs is their antiviral activity; viral infections result in induction of the transcription of the IFN-alpha and IFN-beta genes. Recently we isolated the gene encoding a transcription factor, IRF-1, that may play a part in the induction of IFN genes. Interestingly, the IRF-1 gene itself is virus-inducible, suggesting the importance of de novo production of IRF-1 in IFN gene induction. Here we show that high-level expression of the cloned mouse IRF-1 gene in monkey COS cells results in the induction of endogenous IFN-alpha and IFN-beta genes without viral stimulation. Furthermore, we demonstrate the induction of these genes by an IRF-1/yeast GAL4 chimaeric transcription factor. This may be the first demonstration of the specific induction of silent chromosomal genes by transfection of a single transcription factor gene in mammalian cells.

• Evidence for a nuclear factor(s), IRF-1, mediating induction and silencing properties to human IFN-beta gene regulatory elements.

  T Fujita, J Sakakibara, Y Sudo, M Miyamoto, Y Kimura, T Taniguchi

  Transcription of the human interferon-beta (IFN-beta) gene is induced by a variety of agents such as viruses, dsRNA and some cytokines. In this study, we describe a nuclear factor, termed interferon regulatory factor-1 (IRF-1), that is involved in the transcription of IFN-beta and possibly other genes. We demonstrate that IRF-1 functions in virus-induced transcription by interacting with previously identified, IFN-beta regulatory DNA elements. Our data suggest that IRF-1 participates in the transient formation of an induction-specific complex(es) with the regulatory elements. IRF-1 may also be involved in silencing the function of the SV40 enhancer juxtaposed to the regulatory elements in uninduced cells.

• Regulated expression of a gene encoding a nuclear factor, IRF-1, that specifically binds to IFN-beta gene regulatory elements.

  M Miyamoto, T Fujita, Y Kimura, M Maruyama, H Harada, Y Sudo, T Miyata, T Taniguchi

  Expression of the interferon-beta (IFN-beta) gene is induced by a variety of agents, including viruses. Evidence has been provided that a mouse nuclear factor, termed interferon regulatory factor-1 (IRF-1), specifically binds to the upstream regulatory region of the human IFN-beta gene and mediates virus-induced transcription of the gene. In this study, we describe the molecular cloning and characterization of the mouse and human cDNAs encoding IRF-1. Our results suggest that IRF-1 is also involved in the regulation of other genes such as IFN-alpha and MHC class I genes. Surprisingly, IRF-1 gene expression is dramatically induced by Newcastle disease virus in mouse L929 cells and by Concanavalin A in spleen cells. We show here that the IRF-1 gene possesses virus-inducible promoter.
