Anti-AGPAT4 antibodies are used in the immunodetection of the protein 1-acylglycerol-3-phosphate O-acyltransferase 4. In humans, the canonical protein has a reported length of 378 amino acid residues and a mass of 44 kDa. Its subcellular localization is in the ER. Up to 2 different isoforms have been reported for this protein. It is reported to be widely expressed with highest levels in skeletal muscle, followed by heart, liver, prostate and thymus. It is a member of the 1-acyl-sn-glycerol-3-phosphate acyltransferase protein family. Synonyms for this target antigen include 1-AGP acyltransferase 4, 1-AGPAT 4, 1-acylglycerol-3-phosphate O-acyltransferase 4 (lysophosphatidic acid acyltransferase, delta), and 1-acyl-sn-glycerol-3-phosphate acyltransferase delta. AGPAT4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Agpat4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
