Ptdss2 Gene Summary [Mouse]
Enables CDP-diacylglycerol-serine O-phosphatidyltransferase activity and L-serine-phosphatidylethanolamine phosphatidyltransferase activity. Acts upstream of or within phosphatidylserine biosynthetic process. Located in endoplasmic reticulum membrane. Is expressed in several structures, including genitourinary system; hemolymphoid system; liver; lung; and nervous system. Orthologous to human PTDSS2 (phosphatidylserine synthase 2).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Ptdss2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
