SUBCELLULAR LOCALIZATION	plasma membrane

	intracellular,cytoplasm,organelle,mitochondria
	intracellular,cytoplasm,cytosolic
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

INTERACTION

DNA

RNA

small molecule

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
