Anti-Prominin 2 antibodies are used for the immunodetection of the protein encoded by the PROM2 gene. In humans, the canonical protein has a reported length of 834 amino acid residues and a mass of 91.9 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of the Prominin protein family, it is known to be involved with protein phosphorylation. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include prominin-like protein 2 and prominin-related protein. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
