Anti-NIBAN2 antibodies are used in the immunodetection of the protein niban apoptosis regulator 2. In humans, the canonical protein has a reported length of 746 amino acid residues and a mass of 84.1 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Niban protein family, NIBAN2 is believed to play a role in apoptosis suppression. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include family with sequence similarity 129 member B, melanoma invasion by ERK, niban-like protein 1, and protein Niban 2. NIBAN2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species.
