Acidic phospholipase A2 5

UniProtKB accession:  P82896

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Snake venom phospholipase A2 (PLA2) that inhibits platelet aggregation induced by ADP, arachidonic acid and PAF (Ref.1). Acts in a enzymatic independent manner on a proteinase-activated receptor (PAR1, F2R) to evoke calcium release through the inositol 1,4,5-trisphosphate receptor (ITPR1, IP3R) and induces mouse aorta contraction (PubMed:25447533). PAR1, phospholipase C and IP3R inhibitors suppress PA2-induced aorta contraction (PubMed:25447533). PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.
