Group XV phospholipase A2 (PLA2G15)

Has transacylase and calcium-independent phospholipase A2 activity (PubMed:20410020, PubMed:23958596). Catalyzes the formation of 1-O-acyl-N-acetylsphingosine and the concomitant release of a lyso-phospholipid (PubMed:11790796, PubMed:25727495).

Has high activity with 1-palmitoyl-2-oleoyl-sn-glycero-3- phosphocholine (POPC) and 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC), catalyzing the transfer of oleic acid to N-acetyl- sphingosine. Required for normal phospholipid degradation in alveolar and peritoneal macrophages and in spleen (By similarity).
