Summary: Enables glycerol-3-phosphate O-acyltransferase activity. Involved in several processes, including cellular response to insulin stimulus; glycerolipid biosynthetic process; and positive regulation of triglyceride biosynthetic process. Located in mitochondrial outer membrane. Biomarker of metabolic dysfunction-associated steatotic liver disease; nephrotic syndrome; and obesity. Orthologous to human GPAM (glycerol-3-phosphate acyltransferase, mitochondrial). [provided by Alliance of Genome Resources, Nov 2024]

ChREBP and SREBP-1 bind to the mtGPAT distal promoter.
Title: Transcriptional regulation of mitochondrial glycerophosphate acyltransferase is mediated by distal promoter via ChREBP and SREBP-1.
Taken together, the results suggest that there are two promoters for rat mtGPAT gene and that the transcriptional regulation is mediated through the distal promoter.
Title: The presence of distal and proximal promoters for rat mitochondrial glycerol-3-phosphate acyltransferase.
These results demonstrate that two pools of GPAT1 are present in rat liver mitochondria: an active one, located in outer mitochondrial membrane and a less active one, located in membranes associated with both mitochondria and endoplasmic reticulum.
Title: Mitochondrial glycerol-3-P acyltransferase 1 is most active in outer mitochondrial membrane but not in mitochondrial associated vesicles (MAV).

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.
