Anti-TMEM258 antibodies are used in the immunodetection of the protein transmembrane protein 258. In humans, the canonical protein has a reported length of 79 amino acid residues and a mass of 9.1 kDa. Its subcellular localization is in the membrane, ER, and cytoplasm. It is ubiquitously expressed across many tissue types. A member of the OST5 protein family, TMEM258 is a known 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. Synonyms for this target antigen include Kud, Kuduk, UPF0197 transmembrane protein C11orf10, dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit TMEM258, oligosaccharyl transferase subunit TMEM258, and C11orf10. Immunohistochemistry is the most common application for the TMEM258 antibodies listed below. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
