Alpha 1,4-galactosyltransferase, or, A4GALT, is a human gene. Other names include: Lactosylceramide 4-alpha-galactosyltransferase; Alpha-1,4-galactosyltransferase; Alpha4Gal-T1; CD77 synthase; Globotriaosylceramide synthase; Gb3 synthase; P1/Pk synthase; UDP-galactose:beta-D-galactosyl-beta1-R 4-alpha-D-galactosyltransferase; Lactosylceramide 4-alpha-galactosyltransferase ; A14GALT; A4GALT1; Gb3S; P(k); P1PK. The encoded protein is an enzyme with an amino acid length of 353 and a mass of 40.5 kDa. Alpha 1,4-galactosyltransferase is a member of the Glycosyltransferase 32 family. This gene shares homology with other species, including: Mouse, Rat, Frog, Chicken.
