Anti-CDGIF antibodies enable researchers to detect and measure the CDGIF antigen in biological samples. This target is a reported synonym of the MPDU1 gene, which encodes mannose-P-dolichol utilization defect 1. This protein is known to function in protein folding, among other biological roles. The human version of CDGIF has a canonical amino acid length of 247 residues and a protein mass of 26.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane of cells. CDGIF is a member of the MPDU1 (TC 2.A.43.3) protein family.
