Anti-ALG2 alpha-1,3/1,6-mannosyltransferase antibodies are used for the immunodetection of the protein encoded by the ALG2 gene. In humans, the canonical protein has a reported length of 416 amino acid residues and a mass of 47.1 kDa. Its subcellular localization is in the membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Glycosyltransferase group 1 protein family, it is known to be involved with protein glycosylation. The gene encoding this protein is implicated in Congenital disorder of glycosylation. Other names for this target antigen include GDP-Man:Man(1)GlcNAc(2)-PP-Dol alpha-1,3-mannosyltransferase, GDP-Man:Man(1)GlcNAc(2)-PP-dolichol mannosyltransferase, GDP-Man:Man(2)GlcNAc(2)-PP-Dol alpha-1,6-mannosyltransferase, and alpha-1,3/1,6-mannosyltransferase ALG2. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
