1.A.4.5.13
TRPM8 of the collared flycatcher of 1103 aas. It is 83% identical to the human ortholog. Its structure has been determined to ~4.1 Å resolution by cryo EM (Yin et al. 2018). The structure reveals a three-layered architecture. The amino-terminal domain with a fold
distinct among known TRP structures, together with the carboxyl-terminal
region, forms a large two-layered cytosolic ring that extensively
interacts with the transmembrane channel layer. The structure suggests
that the menthol-binding site is located within the voltage-sensor-like
domain and thus provides a structural glimpse of the design principle of
the molecular transducer for cold and menthol sensation (Yin et al. 2018).
