Identification
NameLysophospholipase 1
Synonyms
  • Phospholipase B 1
Gene NamePLB1
Enzyme Class
Biological Properties
General FunctionInvolved in metabolic process
Specific FunctionSequentially removes both fatty acyl groups from diacylglycerophospholipids and therefore has both phospholipase A and lysophospholipase activities. Substrate preference is phosphatidylserine > phosphatidylinositol >> phosphatidylcholine > phosphatidylethanolamine
Cellular LocationCell membrane; Lipid-anchor, GPI-anchor (Probable)
