Contributes to mechanosensitive currents in nocireceptors and detecting mechanical pain stimuli (By similarity). May also be required for efficient adipogenesis (PubMed:26024229).[UniProtKB:Q8C1E7]<ref>PMID:26024229</ref>

== Publication Abstract from PubMed ==
 +
TACAN is an ion channel-like protein that may be involved in sensing mechanical pain. Here, we present the cryo-electron microscopic structure of human TACAN (hTACAN). hTACAN forms a dimer in which each protomer consists of a transmembrane globular domain (TMD) containing six helices and an intracellular domain (ICD) containing two helices. Molecular dynamic simulations suggest that each protomer contains a putative ion conduction pore. A single-point mutation of the key residue Met207 greatly increases membrane pressure-activated currents. In addition, each hTACAN subunit binds one cholesterol molecule. Our data show the molecular assembly of hTACAN and suggest that wild-type hTACAN is in a closed state.
