Species: Homo sapiens

Gene Type: protein coding
Gene ID: 9791

About PTDSS1

Cytogenetic location: 8q22.1 Genomic coordinates (GRCh38): 8:96,261,902-96,336,995 (from NCBI)

This gene has 6 transcripts (splice variants), 271 orthologues, 1 paralogue and is associated with 3 phenotypes. Ubiquitous expression in heart (RPKM 35.2), placenta (RPKM 27.0) and 25 other tissues.

Summary

The 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]
