    Impaired B and T cell antigen receptor signaling in p110delta PI 3-kinase mutant mice (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-07-20
    Description: Class IA phosphoinositide 3-kinases (PI3Ks) are a family of p85/p110 heterodimeric lipid kinases that generate second messenger signals downstream of tyrosine kinases, thereby controlling cell metabolism, growth, proliferation, differentiation, motility, and survival. Mammals express three class IA catalytic subunits: p110alpha, p110beta, and p110delta. It is unclear to what extent these p110 isoforms have overlapping or distinct biological roles. Mice expressing a catalytically inactive form of p110delta (p110delta(D910A)) were generated by gene targeting. Antigen receptor signaling in B and T cells was impaired and immune responses in vivo were attenuated in p110delta mutant mice. They also developed inflammatory bowel disease. These results reveal a selective role for p110delta in immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okkenhaug, Klaus -- Bilancio, Antonio -- Farjot, Geraldine -- Priddle, Helen -- Sancho, Sara -- Peskett, Emma -- Pearce, Wayne -- Meek, Stephen E -- Salpekar, Ashreena -- Waterfield, Michael D -- Smith, Andrew J H -- Vanhaesebroeck, Bart -- New York, N.Y. -- Science. 2002 Aug 9;297(5583):1031-4.

    Phosphatidylinositol 3-kinase encoded by yeast VPS34 gene essential for protein sorting (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-02
    Description: The VPS34 gene product (Vps34p) is required for protein sorting to the lysosome-like vacuole of the yeast Saccharomyces cerevisiae. Vps34p shares significant sequence similarity with the catalytic subunit of bovine phosphatidylinositol (PI) 3-kinase [the 110-kilodalton (p110) subunit of PI 3-kinase], which is known to interact with activated cell surface receptor tyrosine kinases. Yeast strains deleted for the VPS34 gene or carrying vps34 point mutations lacked detectable PI 3-kinase activity and exhibited severe defects in vacuolar protein sorting. Overexpression of Vps34p resulted in an increase in PI 3-kinase activity, and this activity was specifically precipitated with antisera to Vps34p. VPS34 encodes a yeast PI 3-kinase, and this enzyme appears to regulate intracellular protein trafficking decisions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schu, P V -- Takegawa, K -- Fry, M J -- Stack, J H -- Waterfield, M D -- Emr, S D -- New York, N.Y. -- Science. 1993 Apr 2;260(5104):88-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cellular and Molecular Medicine, University of California, San Diego, School of Medicine.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8385367" target="_blank"〉PubMed〈/a〉

    Expression of a platelet-derived growth factor-like protein in simian sarcoma virus transformed cells (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-09-30
    Description: The near identity of the partial amino acid sequence of human platelet-derived growth factor (PDGF) and that predicted for p28sis, the putative transforming protein of the simian sarcoma virus (SSV), suggests expression of a growth factor activity may be central for transformation by SSV. It is now reported that SSV-transformed cells but not control cells contain a growth factor activity that is identical to PDGF in immunoassay, in mitogenic dose response, and in specific mitogenic activity. The protein immunoprecipitated by antiserum to human PDGF has an apparent molecular weight of 20,000, identical to that of p20sis, the putative intracellular degradation product of p28sis. The results support the concept that expression of a PDGF-like molecule, which appears to be the product of the viral-sis gene, is responsible for the abnormal regulation of growth is SSV-transformed cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deuel, T F -- Huang, J S -- Huang, S S -- Stroobant, P -- Waterfield, M D -- New York, N.Y. -- Science. 1983 Sep 30;221(4618):1348-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6310754" target="_blank"〉PubMed〈/a〉

    The complete primary structure of protein kinase C--the major phorbol ester receptor (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-22
    Description: Protein kinase C, the major phorbol ester receptor, was purified from bovine brain and through the use of oligonucleotide probes based on partial amino acid sequence, complementary DNA clones were derived from bovine brain complementary DNA libraries. Thus, the complete amino acid sequence of bovine protein kinase C was determined, revealing a domain structure. At the amino terminal is a cysteine-rich domain with an internal duplication; a putative calcium-binding domain follows, and there is at the carboxyl terminal a domain that shows substantial homology, but not identity, to sequences of other protein kinase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parker, P J -- Coussens, L -- Totty, N -- Rhee, L -- Young, S -- Chen, E -- Stabel, S -- Waterfield, M D -- Ullrich, A -- New York, N.Y. -- Science. 1986 Aug 22;233(4766):853-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3755547" target="_blank"〉PubMed〈/a〉

    Multiple, distinct forms of bovine and human protein kinase C suggest diversity in cellular signaling pathways (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-08-22
    Description: A new family of protein kinase C-related genes has been identified in bovine, human, and rat genomes. The alpha-, beta-, and gamma-type protein kinase sequences are highly homologous, include a kinase domain, and potential calcium-binding sites, and they contain interspersed variable regions. The corresponding genes are located on distinct human chromosomes; the possibility of even greater genetic complexity of this gene family is suggested by Northern and Southern hybridization analyses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coussens, L -- Parker, P J -- Rhee, L -- Yang-Feng, T L -- Chen, E -- Waterfield, M D -- Francke, U -- Ullrich, A -- New York, N.Y. -- Science. 1986 Aug 22;233(4766):859-66.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3755548" target="_blank"〉PubMed〈/a〉
