Anti-MAGT1 antibodies are used in the immunodetection of the protein magnesium transporter 1. In humans, the canonical protein has a reported length of 335 amino acid residues and a mass of 38 kDa. Its subcellular localization is in the ER and cell membrane. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the OST3/OST6 protein family, MAGT1 is reported to be an accessory component of the STT3B-containing form 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 dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit MAGT1, implantation-associated protein, oligosaccharyl transferase subunit MAGT1, and magnesium transporter protein 1. A number of MAGT1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
