In these reports, mutations in Lec35/MPDU1 disrupt the proper utilization of sugar donors, such as mannose-P-dolichol and glucose-P-dolichol, leading to impaired lipid‐linked oligosaccharide biosynthesis and consequently, to a congenital disorder of glycosylation. These findings emphasize that the Lec35/MPDU1 protein is critical for ensuring the correct orientation and availability of dolichol‐linked sugars required in multiple glycosylation reactions essential for protein folding and membrane anchoring."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nAn independent study (3) explored regulatory mechanisms in gastric cancer progression; however, none of the provided abstracts specifically address or mention a function for SND1-IT1.
