Unmasking subtype-dependent susceptibility to C-type inactivation in mammalian Kv1 channels.

Abstract excerpt

Shaker potassium channels have been an essential model for studying inactivation of ion channels and shaped our earliest understanding of N-type vs. C-type mechanisms. In early work describing C-type inactivation, López-Barneo and colleagues systematically characterized numerous mutations of Shaker residue T449, demonstrating that this position was a key determinant of C-type inactivation rate. In most of the...
