引用 | ジャーナル: Nat Struct Mol Biol / 年: 2021タイトル: Heat-dependent opening of TRPV1 in the presence of capsaicin. 著者: Do Hoon Kwon / Feng Zhang / Yang Suo / Jonathan Bouvette / Mario J Borgnia / Seok-Yong Lee / ![]() 要旨: Transient receptor potential vanilloid member 1 (TRPV1) is a Ca-permeable cation channel that serves as the primary heat and capsaicin sensor in humans. Using cryo-EM, we have determined the ...Transient receptor potential vanilloid member 1 (TRPV1) is a Ca-permeable cation channel that serves as the primary heat and capsaicin sensor in humans. Using cryo-EM, we have determined the structures of apo and capsaicin-bound full-length rat TRPV1 reconstituted into lipid nanodiscs over a range of temperatures. This has allowed us to visualize the noxious heat-induced opening of TRPV1 in the presence of capsaicin. Notably, noxious heat-dependent TRPV1 opening comprises stepwise conformational transitions. Global conformational changes across multiple subdomains of TRPV1 are followed by the rearrangement of the outer pore, leading to gate opening. Solvent-accessible surface area analyses and functional studies suggest that a subset of residues form an interaction network that is directly involved in heat sensing. Our study provides a glimpse of the molecular principles underlying noxious physical and chemical stimuli sensing by TRPV1, which can be extended to other thermal sensing ion channels. | ||||||
