Anti-Fucosyltransferase 8 antibodies are used in the immunodetection of the protein encoded by the FUT8 gene. In humans, the canonical protein has a reported length of 575 amino acid residues and a mass of 66.5 kDa. Its subcellular localization is in the golgi. Alternative splicing is reported to yield 4 different isoforms for this protein. A member of the Glycosyltransferase 23 protein family, it is known to catalyze the addition of fucose in alpha 1-6 linkage to the first GlcNAc residue, next to the peptide chains in N-glycans. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include CDGF1, alpha-(1,6)-fucosyltransferase, GDP-L-Fuc:N-acetyl-beta-D-glucosaminide alpha1,6-fucosyltransferase, GDP-fucose--glycoprotein fucosyltransferase, and CDGF.
