Human Gene AGPAT1 (uc011hct.1) Description and Page Index
Description: Homo sapiens 1-acylglycerol-3-phosphate O-acyltransferase 1 (AGPAT1), transcript variant 1, mRNA. RefSeq Summary (NM_032741): 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.

ID:PLCA_HUMAN DESCRIPTION: RecName: Full=1-acyl-sn-glycerol-3-phosphate acyltransferase alpha; EC=18.104.22.168; 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; Flags: Precursor; 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: Endoplasmic reticulum membrane; Multi-pass membrane protein. TISSUE SPECIFICITY: Widely expressed. Expressed in adipose tissue and at high levels in testis and pancreas. Expressed at lower levels in tissues such as heart, brain, placenta, kidney, lung, spleen, thymus, prostate, ovary, intestine, colon, leukocyte and liver. 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; Note=Translation N-terminally extended;

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.
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.
