Anti-membrane integral NOTCH2 associated receptor 2 antibodies are used for the immunodetection of the protein encoded by the MINAR2 gene. 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, it 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. Other names 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. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
