Anti-TMC antibodies enable researchers to detect and measure the TMC antigen in biological samples. This target is a reported synonym of the STT3A gene, which encodes STT3 oligosaccharyltransferase complex catalytic subunit A. This protein is a known catalytic subunit of the oligosaccharyl transferase (OST) complex that catalyzes the initial transfer of a defined glycan (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol-pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation. The human version of TMC has a canonical amino acid length of 705 residues and a protein mass of 80.5 kilodaltons. It is reported to be localized in the ER of cells and widely expressed in many tissue types. Other names for this target antigen include CDG1WAD, CDG1WAR, and ITM1. Indicated applications for TMC antibodies listed below include ELISA and Immunohistochemistry.
