Integrin glycosylation

Nettet13. apr. 2024 · It can be partly attributed to the different glycosylation of α3β1 integrin. Only BC cells showed the presence of β1,6-branched N-glycans on both α3 and β1 integrin subunits [38,39], whereas the level of the α3 integrin subunit expression in both cell lines showed no statistically significant differences . NettetThus, glycosylation of collagen can modulate integrin binding, and levels of glycosylation could be altered by reduction in expression of glycosylation enzymes but most likely not by extracellular deglycosylation activity.
