Anti-ALG11 alpha-1,2-mannosyltransferase antibodies are used for the immunodetection of the protein encoded by the ALG11 gene. In humans, the canonical protein has a reported length of 492 amino acid residues and a mass of 55.7 kDa. Its subcellular localization is in the ER. It is a member of the Glycosyltransferase group 1 protein family. Post-translational modifications have been described, including glycosylation. The gene encoding this protein is implicated in Congenital disorder of glycosylation. Other names for this target antigen include GDP-Man:Man(3)GlcNAc(2)-PP-dolichol alpha-1,2-mannosyltransferase, asparagine-linked glycosylation 11, alpha-1,2-mannosyltransferase homolog, and GDP-Man:Man(3)GlcNAc(2)-PP-Dol alpha-1,2-mannosyltransferase. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
