Citation | Journal: Proc Natl Acad Sci U S A / Year: 2019 Title: Structural insight into TRPV5 channel function and modulation. Authors: Shangyu Dang / Mark K van Goor / Daniel Asarnow / YongQiang Wang / David Julius / Yifan Cheng / Jenny van der Wijst / Abstract: TRPV5 (transient receptor potential vanilloid 5) is a unique calcium-selective TRP channel essential for calcium homeostasis.

Unlike other TRPV channels, TRPV5 and its close homolog, TRPV6, do not exhibit thermosensitivity or ligand-dependent activation but are constitutively open at physiological membrane potentials and modulated by calmodulin (CaM) in a calcium-dependent manner. Here we report high-resolution electron cryomicroscopy structures of truncated and full-length TRPV5 in lipid nanodiscs, as well as of a TRPV5 W583A mutant and TRPV5 in complex with CaM. These structures highlight the mechanism of calcium regulation and reveal a flexible stoichiometry of CaM binding to TRPV5. | |||||||||||||||||||||||||||
