TRPV channels share general mechanisms of activation while exhibiting subtype-specific features along the activation pathway that can determine their apparent sensitivity to stimuli.
The auxiliary protein Stargazin limits the conformational dynamics of AMPA-type glutamate receptors in cell membranes, as revealed by 'molecular rulers' deployed on the seconds to milliseconds timescale.
Synthetic PPARγ ligands push and cobind with natural endogenous ligands, instead of compete and displace, which synergistically affects the structure and function of PPARγ.
Membrane mechanics predict that the ion channel Piezo recruits the surrounding membrane to amplify its sensitivity to changes in membrane tension, with greatest sensitivity in the low-tension regime.

A dual-color TIRFM study reveals a new form of inflammatory regulation, in which a lipid kinase and ion channel reciprocally regulate each other to amplify the response to painful stimuli.
Dipak N Patil, Erumbi S Rangarajan ... Kirill A Martemyanov
Atomic details on structural organization and conformational dynamics of the key regulator of neuronal signaling shed light on its allosteric regulation and role in regulating cellular pathways.
