PLC γ1 (phospho Tyr771) Rabbit Polyclonal Antibody

The protein encoded by this gene catalyzes the formation of inositol 1,4,5-trisphosphate and diacylglycerol from phosphatidylinositol 4,5-bisphosphate. This reaction uses calcium as a cofactor and plays an important role in the intracellular transduction of receptor-mediated tyrosine kinase activators. For example, when activated by SRC, the encoded protein causes the Ras guanine nucleotide exchange factor RasGRP1 to translocate to the Golgi, where it activates Ras. Also, this protein has been shown to be a major substrate for heparin-binding growth factor 1 (acidic fibroblast growth factor) -activated tyrosine kinase. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008], catalytic activity:1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H (2) O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol., cofactor:Calcium., domain:The SH3 domain mediates interaction with CLNK (By similarity) . The SH3 domain also mediates interaction with RALGPS1., function:PLC-gamma is a major substrate for heparin-binding growth factor 1 (acidic fibroblast growth factor) -activated tyrosine kinase., PTM:The receptor-mediated activation of PLC-gamma-1 and PLC-gamma-2 involves their phosphorylation by tyrosine kinases in response to ligation of a variety of growth factor receptors and immune system receptors., PTM:Ubiquitinated by CBLB in activated T-cells., similarity:Contains 1 C2 domain., similarity:Contains 1 EF-hand domain., similarity:Contains 1 PH domain., similarity:Contains 1 PI-PLC X-box domain., similarity:Contains 1 PI-PLC Y-box domain., similarity:Contains 1 SH3 domain., similarity:Contains 2 PH domains., similarity:Contains 2 SH2 domains., similarity:Contains 3 PH domains., subunit:Interacts with AGAP2 via its SH3 domain (By similarity) . Interacts with phosphorylated LAT upon TCR activation. Interacts with the Pro-rich domain of TNK1 via its SH3 domain. Associates with BLNK, VAV1, GRB2 and NCK1 in a B-cell antigen receptor-dependent fashion. Interacts with CBLB in activated T-cells; which inhibits phosphorylation. Interacts with SHB. Interacts via its SH3 domain with the Arg/Gly-rich-flanked Pro-rich domains of KHDRBS1/SAM68. This interaction is selectively regulated by arginine methylation of KHDRBS1/SAM68. Interacts with INPP5D/SHIP1 and CLNK (By similarity) . Interacts with RALGPS1. Interacts (via SH3 domain) with HEV ORF3 protein.
