機能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.
配列類似性Contains 1 SH2 domain.
ドメインThe N-terminal proline-rich region interacts with the SH3 domain of PLCG1. The SH2 domain is important for restoration of BCR-induced calcium response and JNK2 activation in BLNK-deficient DT40 cells expressing LAT.
翻訳後修飾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.
