General annotation (Comments)

Function

Catalyzes a base-exchange reaction in which the polar head group of phosphatidylcholine is replaced by L-serine By similarity.

Pathway

Phospholipid metabolism; phosphatidylserine biosynthesis.

Subcellular location

Membrane; Multi-pass membrane protein.

Miscellaneous

May provide a precursor for the biosynthesis of phosphatidylethanolamine. Phosphatidylserine can be decarboxylated to phosphatidylethanolamine.

Sequence similarities

Belongs to the phosphatidyl serine synthase family.
