Anti-PCNX2 antibodies are used in the immunodetection of the protein pecanex 2. In humans, the canonical protein has a reported length of 2137 amino acid residues and a mass of 237.3 kDa. Its subcellular localization is in the membrane. Up to 5 different isoforms have been reported for this protein. A member of the Pecanex protein family, PCNX2 is believed to play a role in tumorigenesis of colorectal carcinomas with high microsatellite instability (MSI-H). Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include pecanex-like protein 2 and pecanex homolog 2. PCNX2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These PCNX2 antibodies are widely used in Western Blot experiments, among other applications.
