Evidence for common structural determinants of activation and inactivation in T-type Ca2+ channels.

Abstract excerpt

One of the most distinctive features of T-type Ca(2+) channels is their fast inactivation. Recent structure-function studies indicate that the rate of macroscopic inactivation of these channels is influenced by several structural components, including intracellular linkers, transmembrane segments, and pore loops. The macroscopic inactivation of T-type channels is partially coupled to activation. It is therefore...
