Anti-TUSC3 antibodies are used in the immunodetection of the protein tumor suppressor candidate 3. In humans, the canonical protein has a reported length of 348 amino acid residues and a mass of 39.7 kDa. Its subcellular localization is in the ER. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in most non-lymphoid cells and tissues examined, including prostate, lung, liver, colon, heart, kidney and pancreas. A member of the OST3/OST6 protein family, TUSC3 is known to act as accessory component of the N-oligosaccharyl transferase (OST) complex which catalyzes the transfer of a high mannose oligosaccharide from a lipid-linked oligosaccharide donor to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains. Synonyms for this target antigen include M33, MRT22, MRT7, MagT2, N33, OST3A, SLC58A2, and D8S1992. A number of TUSC3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
