Integrin receptor ligand binding
NettetAbstract. Integrin α 5 β 1 is a major fibronectin receptor critical for cell migration. Upon complex formation, fibronectin and α 5 β 1 undergo conformational changes. While this is key for cell-tissue connections, its mechanism is unknown. Here, we report cryo–electron microscopy structures of native human α 5 β 1 with fibronectin to 3 ... Nettet3. des. 2014 · The extracellular region is responsible for ligand binding and consists of three functional domains: the Sema domain, structured as a seven-bladed propeller and encompassing the whole α-subunit of the receptor and part of the β-subunit (amino acids 1–518); the cysteine-rich PSI domain (amino acids 519–561, with high homology to …

Nettet29. jan. 2024 · The hybrid domain was the most important component of integrin molecular structure identified in this paper for regulating α V β 6 ligand-binding affinity. Deletion of the hybrid domain resulted in a 50-fold increase in affinity for pro-TGF-β1 of the α V β 6 head compared with the headpiece. Nettet15. jan. 2009 · Although opinion on receptor extension is still varied, there is general agreement that ligand binding is accompanied by an outwards movement of the β-hybrid domain, that this represents the key conformational change in the switch from inactive to active integrin, and that this is a clear indicator of receptor affinity (Rocco et al., 2008; …
