GGDB:

本遺伝子は1型糖鎖抗原(Galb1-4GlcNAc-R)の合成に関与する酵素をコードしている。本酵素は糖供与体UDP-GalからGalをb1-4結合で糖受容体基質(GlcNAc-R)に転移する活性を有する。また、α−ラクトアルブミン(α-lactalbumin)と結合することで、UDP-galactoseを糖供与体として、ガラクトースをグルコースに転移し、LACTOSEの合成にも関与することが知られている。また一方、alpha-lactalbuminの存在下において、UDP-glucoseを糖供与体とし、グルコースをN−アセチルグルコサミンに転移する活性も有していることが知られている。
