Anti-UNK antibodies are used in the immunodetection of the protein unk zinc finger. In humans, the canonical protein has a reported length of 810 amino acid residues and a mass of 88.1 kDa. Its subcellular localization is in the cytoplasm. A member of the Unkempt protein family, UNK is known to be involved with neuronal differentiation and in utero embryonic development. Synonyms for this target antigen include unk family zinc finger, unkempt family zinc finger, unkempt homolog, zinc finger CCCH domain-containing protein 5, and RING finger protein unkempt homolog. UNK gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of UNK antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
