Summary
Enables glycerol-3-phosphate O-acyltransferase activity. Acts upstream of or within several processes, including glycerolipid metabolic process; lipid homeostasis; and negative regulation of activation-induced cell death of T cells. Located in mitochondrion. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human GPAM (glycerol-3-phosphate acyltransferase, mitochondrial). [provided by Alliance of Genome Resources, Apr 2022]
Expression
Broad expression in adrenal adult (RPKM 73.0), subcutaneous fat pad adult (RPKM 64.9) and 23 other tissues See more

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.
