Anti-ZFP42 antibodies are used in the immunodetection of the protein ZFP42 zinc finger protein. In humans, the canonical protein has a reported length of 310 amino acid residues and a mass of 34.8 kDa. Its subcellular localization is in the nucleus. It is reported to be expressed in the kidney, epidermal keratinocytes, prostate epithelial cells, bronchial and small airway lung epithelial cells. A member of the Krueppel C2H2-type zinc-finger protein family, ZFP42 is reported to be involved in reprogramming of X-chromosome inactivation during the acquisition of pluripotency. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include REX1 transcription factor, reduced expression protein 1, zinc finger protein 754, and zinc finger protein 42 homolog. ZFP42 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of ZFP42 antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
