Anti-KOX31 antibodies are used in antigen-specific immunodetection in biological samples. The target KOX31 is a known alias name of the protein zinc finger protein 33A, encoded by the ZNF33A gene in humans. This 810-amino acid residue protein is suspected to be involved in transcriptional regulation. It is localized to the nucleus of the cell. It is reported to be expressed in many tissues, such as the cerebral cortex, vagina, and breast.
