Anti-ACSF1 antibodies enable researchers to detect and measure the ACSF1 antigen in biological samples. This target is a reported synonym of the AACS gene, which encodes acetoacetyl-CoA synthetase. This protein is known to function in fatty acid metabolism, among other biological roles. The human version of ACSF1 has a canonical amino acid length of 672 residues and a protein mass of 75.1 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. ACSF1 is a member of the ATP-dependent AMP-binding enzyme protein family.
