Anti-KOX2 antibodies enable researchers to detect and measure the KOX2 antigen in biological samples. This target is a reported synonym of the ZNF33A gene, which encodes zinc finger protein 33A. This protein is known to function in the regulation of transcription, among other biological roles. The human version of KOX2 has a canonical amino acid length of 810 residues and a protein mass of 94.4 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus of cells and notably expressed in many tissues, such as the cerebral cortex, vagina, and breast. KOX2 is a member of the Krueppel C2H2-type zinc-finger protein family.
