Gene Namephosphatidylserine synthase 1
Gene Symbol PTDSS1
SynonymsLMHD; PSS1; PSSA;
Alternate namesphosphatidylserine synthase 1; PSS-1; ptdSer synthase 1; serine-exchange enzyme I;

EC Number2.7.8.29
SummaryThe protein encoded by this gene catalyzes the formation of phosphatidylserine from either phosphatidylcholine or phosphatidylethanolamine. Phosphatidylserine localizes to the mitochondria-associated membrane of the endoplasmic reticulum, where it serves a structural role as well as a signaling role. Defects in this gene are a cause of Lenz-Majewski hyperostotic dwarfism. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2014]
