DPAGT1 is an enzyme that catalyzes the first step in the dolichol-linked oligosaccharide pathway for glycoprotein biosynthesis. This enzyme belongs to the glycosyltransferase family 4. This protein is an integral membrane protein of the endoplasmic reticulum. The congenital disorder of glycosylation type Ij is caused by mutation in the gene encoding this enzyme. The cDNA encodes a deduced 400-amino acid protein with a calculated molecular mass of 44.7 kD. DPAGT1 contains an N-terminal signal peptide, 2 potential dolichol-binding sequences, and 4 sites for N-glycosylation. It shares 93% amino acid homology with hamster Dpagt, including 100% identity in the dolichol-binding region, and 42% homology with S. cerevisiae GlcNAc-1-P transferase.
Human UDP-N-acetylglucosamine--dolichyl-phosphate N-acetylglucosaminephosphotransferase (DPAGT1) ELISA Kit employs a two-site sandwich ELISA to quantitate DPAGT1 in samples. An antibody specific for DPAGT1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyDPAGT1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for DPAGT1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of DPAGT1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
