Glycans constitute the first molecular landscape encountered by viruses during infection and play fundamental roles in viral attachment, host adaptation, tissue tropism, and immune evasion. Far from being passive components of the cell surface, host glycans actively regulate virus–host interactions by functioning as at...

Cell surface receptors are traditionally conceptualized as discrete molecular entities whose functional diversity arises primarily from gene expression and protein sequence variation. However, this view overlooks the extensive heterogeneity generated by post‐translational modifications, particularly glycosylation, whic...

Post-translational modifications critically regulate extracellular molecular recognition, yet their roles in intrinsically disordered proteins remain poorly defined. Here, we integrate glycoproteomics, NMR, and cellular assays to reveal how glycosylation shapes the interaction network of osteopontin (OPN), a highly g...

CD24 is identified as an innate immune checkpoint that protects colorectal tumors from macrophage-mediated clearance through an evolutionarily conserved recognition mechanism, and its loss enables them to adopt a highly motile, tumor-directed, and functionally engaged state, characterized by increased fusion activity a...

The factors governing protein-specific N-glycosylation remain incompletely understood despite extensive knowledge of the biosynthetic machinery involved in glycan assembly. In particular, the contribution of the protein sequence itself to the final glycosylation pattern has received comparatively little attention. Here...
