Human Gene AGPAT1 (uc003oae.3) Description and Page Index
  Description: Homo sapiens 1-acylglycerol-3-phosphate O-acyltransferase 1 (AGPAT1), transcript variant 1, mRNA.
RefSeq Summary (NM_006411): This gene encodes an enzyme that converts lysophosphatidic acid (LPA) into phosphatidic acid (PA). LPA and PA are two phospholipids involved in signal transduction and in lipid biosynthesis in cells. This enzyme localizes to the endoplasmic reticulum. This gene is located in the class III region of the human major histocompatibility complex. Alternative splicing results in two transcript variants encoding the same protein. [provided by RefSeq, Jul 2008].

DESCRIPTION: RecName: Full=1-acyl-sn-glycerol-3-phosphate acyltransferase alpha; EC=; AltName: Full=1-acylglycerol-3-phosphate O-acyltransferase 1; Short=1-AGP acyltransferase 1; Short=1-AGPAT 1; AltName: Full=Lysophosphatidic acid acyltransferase alpha; Short=LPAAT-alpha; AltName: Full=Protein G15;
FUNCTION: Converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating an acyl moiety at the sn-2 position of the glycerol backbone.
CATALYTIC ACTIVITY: Acyl-CoA + 1-acyl-sn-glycerol 3-phosphate = CoA + 1,2-diacyl-sn-glycerol 3-phosphate.
PATHWAY: Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 2/3.
SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein (Potential).
DOMAIN: The HXXXXD motif is essential for acyltransferase activity and may constitute the binding site for the phosphate moiety of the glycerol-3-phosphate (By similarity).
SIMILARITY: Belongs to the 1-acyl-sn-glycerol-3-phosphate acyltransferase family.
SEQUENCE CAUTION: Sequence=AAB47493.1; Type=Erroneous initiation;

ModBase Predicted Comparative 3D Structure on Q99943
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
