Disease relevance of Pik3cd

 

Psychiatry related information on Pik3cd

  • AVP was also effective in reducing the maximal electroshock (MES) induced convulsive time and this protective effect was blocked by PI-3 kinase inhibitors [6].
 

High impact information on Pik3cd

  • We find that p110alpha is the primary insulin-responsive PI3-K in cultured cells, whereas p110beta is dispensable but sets a phenotypic threshold for p110alpha activity [7].
  • These results suggested that PI3-kinase binds two phosphotyrosine residues, each located in a 5 aa motif with an essential methionine at the fourth position C-terminal to the tyrosine [8].
  • Therefore, GAP and PI3-kinase interact with the receptor by binding to different phosphotyrosine-containing sequence motifs [8].
  • Mutation of the binding site for GAP prevented the receptor from associating with or phosphorylating GAP, but had no effect on PI3-kinase binding and little effect on DNA synthesis [8].
  • Point mutations at these sites caused a selective elimination of PI3-kinase binding and loss of PDGF-stimulated DNA synthesis [8].
 

Chemical compound and disease context of Pik3cd

 

Biological context of Pik3cd

  • In addition, the p110delta catalytic domain contains unique potential protein-protein interaction modules such as a Pro-rich region and a basic-region leucine-zipper (bZIP)-like domain [14].
  • Like p110alpha and p110beta, other class I PI3Ks, p110delta displays a broad phosphoinositide lipid substrate specificity and interacts with SH2/SH3 domain-containing p85 adaptor proteins and with GTP-bound Ras [14].
  • Macrophages from mice expressing a catalytically inactive form of p110delta showed no defect in the phagocytosis of apoptotic cells and IgG-opsonized particles, confirming the lack of a major role for p110delta in this process [15].
  • Thus, p110delta plays a critical role in B cell homeostasis and function [16].
  • Here, in vitro phospholipase assays establish that the phosphatidylinositol 3-kinase (PI 3-kinase) lipid product, phosphatidylinositol 3,4,5-triphosphate, further stimulates phospholipase Cgamma2 that has been activated by conformational changes associated with tyrosine phosphorylation or low pH [17].
 

Anatomical context of Pik3cd

 

Associations of Pik3cd with chemical compounds

  • The more pronounced inhibitory effect of LY294002 and wortmannin indicates that other isoforms of PI 3-kinase play a more significant role in signalling by the two platelet glycoprotein receptors [20].
  • Role of the p110delta PI 3-kinase in integrin and ITAM receptor signalling in platelets [20].
  • This indicates a requirement for Ins(1,4,5)P3 to initiate and sustain Ca2+ responses even when PI 3-kinase is fully active [17].
  • Antigen-induced cell ruffling, a calcium-independent event, is blocked by injection of p110beta and p110delta antibodies, but not by injection of 5-phosphatase I, heparin, or anti-p110alpha antibodies [17].
  • p110beta and p110delta phosphatidylinositol 3-kinases up-regulate Fc(epsilon)RI-activated Ca2+ influx by enhancing inositol 1,4,5-trisphosphate production [17].
