Description Not Available
Synonyms
  1. Phospholipase A2 group IVB
  2. cPLA2-beta
Gene Name PLA2G4B
Protein Type Enzyme
Biological Properties
General Function Involved in metabolic process
Specific Function Calcium-dependent phospholipase A2 that selectively hydrolyzes glycerophospholipids in the sn-2 position with a preference for arachidonoyl phospholipids. Has a much weaker activity than PLA2G4A. Isoform 3 has calcium-dependent activity against palmitoyl-arachidonyl-phosphatidylethanolamine and low level lysophospholipase activity but no activity against phosphatidylcholine. Isoform 5 does have activity against phosphatidylcholine.
