Anti-membrane integral NOTCH2 associated receptor 1 antibodies are used for the immunodetection of the protein encoded by the MINAR1 gene. In humans, the canonical protein has a reported length of 916 amino acid residues and a mass of 103 kDa. Its subcellular localization is in the cell membrane. It is reported to be widely expressed including in breast epithelial cells and endothelial cells. A member of the MINAR protein family, it is known to be involved with angiogenesis. Other names for this target antigen include UBTOR, major intrinsically disordered Notch2-binding receptor 1, major intrinsically disordered Notch2-associated receptor 1, ubiquitination and mTOR signaling protein, and KIAA1024. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
