Anti-MINAR2 antibodies are used in the immunodetection of the protein membrane integral NOTCH2 associated receptor 2. In humans, the canonical protein has a reported length of 190 amino acid residues and a mass of 21.6 kDa. Its subcellular localization is in the ER and lysosomes. It is reported to be highly expressed in the auditory hair cells. A member of the MINAR protein family, MINAR2 is known to bind cholesterol and may regulate the distribution and homeostasis of cholesterol in hair cells. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include KIAA1024 like, UPF0258 protein KIAA1024-like, major intrinsically disordered NOTCH2-associated receptor 2, and major intrinsically disordered NOTCH2-binding receptor 1-like. MINAR2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
