Anti-KOX21 antibodies enable researchers to detect and measure the KOX21 antigen in biological samples. This target is a reported synonym of the ZNF37A gene, which encodes zinc finger protein 37A. This protein is known to function in the regulation of transcription, among other biological roles. The human version of KOX21 has a canonical amino acid length of 561 residues and a protein mass of 65.4 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. KOX21 is a member of the Krueppel C2H2-type zinc-finger protein family.
