Comment typeDescription
Catalytic ActivityL-1-phosphatidylethanolamine + L-serine = L-1- phosphatidylserine + ethanolamine.
FunctionCatalyzes a base-exchange reaction in which the polar head group of phosphatidylethanolamine (PE) or phosphatidylcholine (PC) is replaced by L-serine. PTDSS2 is specific for phosphatatidylethanolamine and does not act on phosphatidylcholine (By similarity)
PathwayPhospholipid metabolism; phosphatidylserine biosynthesis.
SimilarityBelongs to the phosphatidyl serine synthase family
Subcellular LocationEndoplasmic reticulum membrane {ECO:0000250}; Multi-pass membrane protein . Note=Highly enriched in the mitochondria-associated membrane (MAM)
