Gene Snapshot
Xiantuan (Xit) is a glucosyl transferase enzyme in the N-glycosylation pathway of the endoplasmic reticulum. It adds the three terminal glucose residues to oligosaccharyl-dolichol before the oligosaccharyl is transferred to newly synthesized proteins. Xit roles include control of gastrulation movements.

Gene Group Membership
GT57 FAMILY OF ALPHA-1,3-GLUCOSYLTRANSFERASES -
GT57 family of alpha-1,3-glucosyltransferases catalyze the addition of terminal (1st and 2nd of the 3) glucose residues from dolichyl-phosphoglucose onto the dolichol glycan precursor before the glycan is transferred from the dolichol carrier to nascent polypeptides. (Adapted from FBrf0224769).
UniProt Contributed Function Data
Adds the second glucose residue to the lipid-linked oligosaccharide precursor for N-linked glycosylation. Transfers glucose from dolichyl phosphate glucose (Dol-P-Glc) onto the lipid-linked oligosaccharide Glc(1)Man(9)GlcNAc(2)-PP-Dol (By similarity). Functions in developmental processes such as germband extension, the apical constriction of mesoderm precursor cells and ventral furrow formation in early embryogenesis prior to gastrulation (PubMed:24681004). Involved in the glycosylation and intracellular distribution of shg (E-cadherin) (PubMed:24681004). Function in cell intercalation in the lateral epidermis during germband extension may be due to its effect on shg (PubMed:24681004).
