  • Currently, 18 subtypes have been reported: 12 are type I (dysfunctional lipid-linked oligosaccharide precursor synthesis), and 6 are type II (dysfunctional trimming/processing of the protein-bound oligosaccharide), including leukocyte adhesion deficiency II (CDG-IIc). (medscape.com)
  • EspG functions as a Rab GTPase-activating protein (Rab-GAP), trapping Rab-GTPases in their inactive GDP bound form, and reducing ER-Golgi transport (of IL-8 and other proteins). (wikipedia.org)
  • Bacterial TPR proteins bound to the C-terminal of Hsc70 through its EEVD motif and this binding inhibited bacterial uptake by TG cells. (biomedcentral.com)
  • Protein-protein interactions also resulted in significant variations in reduced macromolecular diffusion under crowded conditions, while metabolites exhibited significant two-dimensional surface diffusion and altered protein-ligand binding that may reduce the effective concentration of metabolites and ligands in vivo.
