Anti-GLT28D1 antibodies enable researchers to detect and measure the GLT28D1 antigen in biological samples. This target is a reported synonym of the ALG13 gene, which encodes ALG13 UDP-N-acetylglucosaminyltransferase subunit. This protein is known to function in proteolysis, among other biological roles. The human version of GLT28D1 has a canonical amino acid length of 1137 residues and a protein mass of 126.1 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the ER of cells and widely expressed in many tissue types. GLT28D1 is a member of the Glycosyltransferase 28 protein family.
