GALNT12

该基因编码udp-galnac家族的一个成员：多肽n-乙酰半乳糖胺基转移酶，在o-连接蛋白糖基化的初始步骤中催化n-乙酰半乳糖胺（galnac）从udp-galnac转移到多肽受体上的丝氨酸或苏氨酸残基。这个基因的突变与结直肠癌易感性的增加有关。
This gene encodes a member of a family of UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferases, which catalyze the transfer of N-acetylgalactosamine (GalNAc) from UDP-GalNAc to a serine or threonine residue on a polypeptide acceptor in the initial step of O-linked protein glycosylation. Mutations in this gene are associated with an increased susceptibility to colorectal cancer.[provided by RefSeq, Mar 2011]
