Other glycosyltransferases involved in N-linked and mucin-type O-glycan biosynthesis

This target entry refers to a broad category of enzymes, specifically glycosyltransferases, that facilitate the biosynthesis of N-linked and mucin-type O-linked glycans. These enzymes catalyze the transfer of sugar moieties from nucleotide-sugar donors to protein or lipid acceptors, a process essential for proper protein folding, stability, and cellular recognition (KEGG PATHWAY: map00512; UniProt Consortium). N-linked glycosylation occurs on asparagine residues, while mucin-type O-glycosylation involves the attachment of N-acetylgalactosamine to serine or threonine residues. Dysregulation of these enzymes is a hallmark of various diseases; for instance, altered glycan branching and increased sialylation are frequently associated with tumor metastasis and immune evasion in cancer (Moremen et al., 2012). Furthermore, mutations in genes encoding these glycosyltransferases lead to Congenital Disorders of Glycosylation (CDG), characterized by multi-systemic clinical manifestations (Hennet, 2002). Although these enzymes are critical for physiological function, they represent potential therapeutic targets in oncology and inflammatory diseases, where specific inhibitors are being explored to disrupt pathological glycan-mediated interactions.
