Bitterness receptor structure
Web2 days ago · Thus, CRB1 shares general structural features with ancestral nicotinic receptors but is specialized as a bitter tastant receptor through adaptation in key regions, especially the agonist-binding site. WebThey act by binding to the receptor and establishing transient interactions with protein residues that form the binding pocket. Those interactions alter the GPCR structure, leading to a specific downstream signalling response. However, important features responsible for a distinct drug profile (selectivity, signalling outcome, etc.) are still ...
