Anti-ALG8 alpha-1,3-glucosyltransferase antibodies are used for the immunodetection of the protein encoded by the ALG8 gene. In humans, the canonical protein has a reported length of 526 amino acid residues and a mass of 60.1 kDa. Its subcellular localization is in the ER. Alternative splicing is reported to yield 2 different isoforms for this protein. It is a member of the ALG6/ALG8 glucosyltransferase protein family. The gene encoding this protein is implicated in Congenital disorder of glycosylation. Other names for this target antigen include HUSSY-02, asparagine-linked glycosylation 8 alpha-13-glucosyltransferase-like protein, and probable dolichyl pyrophosphate Glc1Man9GlcNAc2 alpha-1,3-glucosyltransferase. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
