FUT3
(redirected from alpha-(1,3/1,4)-fucosyltransferase)FUT3
A gene on chromosome 19q13.3 that encodes a fucosyltransferase with alpha(1,3)-fucosyltransferase and alpha(1,4)-fucosyltransferase activities, which catalyses the addition of fucose to precursor polysaccharides in the last step of Lewis antigen biosynthesis.Molecular pathology
FUT3 mutations are responsible for most Lewis antigen-negative blood group phenotypes.
