Reaction: Phosphorylated BTK phosphorylates PLCG2

- in pathway: Antigen activates B Cell Receptor (BCR) leading to generation of second messengers
Activated BTK (BTK phosphorylated on tyrosine-551 and tyrosine-223) bound to phosphorylated BLNK phosphorylates phospholipase gamma-2 (PKCG2) on tyrosines 753, 759, and 1217 (Rodriguez et al. 2001 and inferred from the rat homolog) thereby activating PLCG2 to hydrolyze phosphatidylinositol 4,5-bisphosphate, yielding the second messengers diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) (Carter et al. 1991, Roifman and Wang 1992, Kim et al. 2004, Sekiya et al. 2004). PLCG2 also binds phosphoinositol 3,4,5-trisphosphate (PIP3) produced by PI3K at the plasma membrane.
