Anti-A-923A4.1 antibodies enable researchers to detect and measure the A-923A4.1 antigen in biological samples. This target is a reported synonym of the ACSM2A gene, which encodes acyl-CoA synthetase medium chain family member 2A. This protein is known to function in carbohydrate metabolism and homeostasis, among other biological roles. The human version of A-923A4.1 has a canonical amino acid length of 577 residues and a protein mass of 64.2 kilodaltons. It is reported to be localized in the mitochondria of cells and notably expressed in the kidney and liver. A-923A4.1 is a member of the ATP-dependent AMP-binding enzyme protein family.
