text
  • WDR26 is required for PLCB2 translocation from the cytosol to the membrane in polarized leukocytes
  • basic FUNCTION
  • phospholipase C, beta 2, phosphatidylinositol specific
  • catalyzing the hydrolysis of phosphatidylinositol 4,5 biphosphate to generate diacylglycerol and inositol 1,4,5 triphosphate
  • mediating a wide variety of cellular stimuli, critical to many chemoattractant elicited responses
  • in differentiating cells, the association of PLCB2 with actin, mediated by the PH domain, seems crucial for catalytic activity
  • plays a pivotal role in G-protein dependent signal transduction in platelets
  • PLCB2, PLCB3 play a critical role in T lymphocyte chemotaxis

    protein
  • binds strongly to PLCdelta1(PLCD1) and inhibits its catalytic activity
  • activity of PLCD1 is controlled by the amount of bound PLCB2 that changes with displacement of the enzyme by heterotrimeric or small G proteins
  • WDR36 associated with PLCB2 and increased the interaction between GNAQ and PLCB2, but prevented sequestration of activated GNAQ by GRK2
  • interaction between SLC9A3R1 and CXCR2 or PLCB2 is PDZ motif-dependent
  • WDR26 is required for PLCB2 translocation from the cytosol to the membrane in polarized leukocytes, and the translocation of PLCB2 was sufficient to cause partial activation of PLCB2
  • cell & other
    REGULATION
    activated by RAC1, that can activate PLCB2 to increase intracellular Ca(2+) levels
