    basic FUNCTION
  • controlling with PTEN heart muscle contractility and cell size and modulating the cardiac response to chronic pressure overload by distinct kinase-dependent and -independent effects
  • playing a role in control of tissue growth
  • having critical roles within the gradient-sensing machinery of a variety of highly motile cells
  • acting as a critical determinant of the proportion of cells that can move
  • plays an essential role in a number of physiological responses, including neutrophil chemotaxis, mast cell degranulation, and cardiac function
  • has two potential regulatory subunits PIK3R5, PIK3R6
  • implicated in a vast array of physiological settings including the activation of different leukocyte species and the regulation of myocardial contractility
  • playing roles in the regulation of some aspects of neutrophil polarization that are relevant to movement, such as integrin-based adhesion and the accumulation of polymerized (F)-actin at the leading-edge
  • having nonredundant function as an important regulator of fibroblast-induced cartilage destruction during chronic destructive arthritis (Hayer 2009)
  • activation by CXCL12 regulates tumor cell adhesion through mechanisms different from those involved in cell invasion (Monte)
  • essential for CCL2-stimulated aortic SMC migration and amplifies cell migration induced by PDGF by an autocrine/paracrine loop involving CCL2 secretion and CCR2 activation
  • PI3KC2B and PIK3CG control distinct steps involved in cell migration supporting the hypothesis that different PI3Ks regulate distinct cellular processes
  • its activity is important for its signaling functions in T cell development, activation, differentiation, and trafficking
  • CELLULAR PROCESS cell life, proliferation/growth
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
  • critical roles for a PI3K3CG-RAP1A-dependent pathway in integrin activation during tumor inflammation
  • a component
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • PTEN
  • PDE3B(inducing cAMP level reduction and negatively modulating cardiac contractility)
  • PIK3R5 is required for G protein-mediated activation of PIK3CG in living cells
  • binding of PIK3R6 to PIK3CG substantially increases the ability of Gbetagamma to stimulate phosphatidylinositol (3,4,5)-trisphosphate (PtdIns(3,4,5)P(3)) production
  • like PIK3R5, PIK3R6 binds to both PIK3CG and Gbetagamma and mediates activation of PIK3CG downstream of G protein-coupled receptors
  • a kinase-independent function of PIK3CG could directly inhibit GSK3 function by preventing the PP2A-PPMT-1 interaction
  • PIK3CG regulates the activity of RALA, which is one of the molecular mechanisms inducing NMDAR dependent long-term depression
