Homo sapiens (Human)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Plays a role in the regulation of immunoreceptor signaling, including PLC-gamma-mediated B-cell antigen receptor (BCR) signaling and FC-epsilon R1-mediated mast cell degranulation. Involved in phosphorylation of LAT (By similarity).By similarity

Post-translational modificationi

Tyrosine-phosphorylated upon BCR cross-linking. Tyrosine phosphorylation at both Tyr-69 and Tyr-96 are required for BCR-induced calcium response and are essential to restore PLCG2-mediated signaling in BLNK-deficient DT40 cells, but this phosphorylation is dispensable in cells expressing LAT. Interacts with the SH2 domain of PLCG1 via phosphorylated Tyr-96 (By similarity).By similarity
