Identification of the cyclic-nucleotide-binding domain as a conserved determinant of ion-channel cell-surface localization.


Mutations of a putative cyclic-nucleotide-binding domain (CNBD) can disrupt the function of the hyperpolarization-activated cyclic-nucleotide-gated channel (HCN2) and the human ether-a-go-go-related gene potassium channel (HERG). Loss of function caused by C-terminal truncation, which includes all or part of the CNBD in HCN and HERG, has been related to… (More)
