Eag domain-CNBHD complex of the mouse EAG1
Introduction:
The KCNH voltage-gated channels are transmembrane channels highly selective for potassium and sensitive to voltage changes in the cells’ membrane potential. They play a crucial roles in repolarization of cells to their resting state and in various diseases such as cardiac long QT syndrome type 2 (LQT2)1, epilepsy2, schizophrenia3 and cancer4. The KCNH channels family has unique intracellular domains that distinguish them from other voltage-gated channels. The amino terminal contains an eag domain and the C-terminus contains a cyclic nucleotide binding homology domain (CNBDH).
