    basic FUNCTION
  • playing a role in RAS activation
  • playing a key role in regulating the formation and stability of integrin alpha(IIb)beta(3) adhesion bonds, necessary for shear activation of platelets
  • with PIK3CA, regulate S-phase entry
  • critical for cell growth and survival
  • plays an essential role in GP6-mediated platelet aggregation and Akt activation
  • positively controls LPS-induced IL12 production through the JNK1-dependent pathway in human macrophages and dendritic cells
  • PIK3R1 and PIK3CB are essential for androgen-stimulated androgen receptor transactivation, and their aberrant expression or activation might play an important role in prostate cancer progression
  • CELLULAR PROCESS cell cycle, progression
    PHYSIOLOGICAL PROCESS coagulation/hemostasis
    text regulation of progression through cell cycle
    PATHWAY
