Critical role for polar residues in coupling leukotriene B4 binding to signal transduction in BLT1

Leukotriene B(4) (LTB(4)) mediates a variety of inflammatory diseases such as asthma, arthritis, atherosclerosis, and cancer through activation of the G-protein-coupled receptor, BLT1. Using in silico molecular dynamics simulations combined with site-directed mutagenesis we characterized the ligand binding site and activation mechanism for BLT1. Mutation of residues predicted as potential ligand contact points in transmembrane […]
