Temperature-dependent gating pathways of rTRPV2. The homo-tetrameric cryo-EM structures of rTRPV2 in the 3rd and 4th closed, open and partially open states in different detergents at 4 °C (PDB ID, 8EKR, 5HI9, 6BO4 and 6BO5, respectively) were used for the model. The partially open state also functions as a partially inactivated state. The corresponding biggest thermorings Grid12, Grid19, Grid12’ and Grid14 are colored red, respectively. All the least-stable noncovalent interactions controlled by those biggest thermorings are indicated by red space fill. The intersubunit interactions are indicated by green space fill.
