Summary
Enables glycerol-3-phosphate O-acyltransferase activity. Involved in glycerol-3-phosphate metabolic process; phospholipid biosynthetic process; and triglyceride biosynthetic process. Located in endoplasmic reticulum. Orthologous to human GPAT3 (glycerol-3-phosphate acyltransferase 3). [provided by Alliance of Genome Resources, Jul 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
