Drafting the calmodulation playbook: Emerging structural insights into transient receptor potential channel regulation by calmodulin

The Journal of Physiology, EarlyView.
Abstract figure legend Calmodulin (CaM) is a ubiquitous calcium (Ca2+) sensor that translates intracellular Ca2+ signals into modulation of hundreds of effector proteins including ion channels. CaM is increasingly recognized as a key regulator of the transient receptor potential (TRP) channel family, yet the underlying ‘calmodulation playbook’ is only ...
