Name Phosphatidylcholine:ceramide cholinephosphotransferase 2
Description Not Available
Synonyms
  1. Sphingomyelin synthase 2
Gene Name SGMS2
Protein Type Enzyme
Biological Properties
General Function Involved in catalytic activity
Specific Function Bidirectional lipid cholinephosphotransferase capable of converting phosphatidylcholine (PC) and ceramide to sphingomyelin (SM) and diacylglycerol (DAG) and vice versa. Direction is dependent on the relative concentrations of DAG and ceramide as phosphocholine acceptors. Directly and specifically recognizes the choline head group on the substrate. Also requires two fatty chains on the choline-P donor molecule in order to be recognized efficiently as a substrate. Does not function strictly as a SM synthase. Required for cell growth
