Kv11.1: Proteins and Enzymes

Human ether-a-go-go related gene (HERG) encodes the pore-forming subunit of the delayed rectifier potassium channel IKr. There are two N-terminal splice variants of HERG include the full-length isoform 1 alpha and the shorter isoform 1 beta. Isoform 1 beta lacks the PAS motif and deactivates at a faster rate than isoform 1alpha. Residues within the C-terminal play a role in channel expression and channel gating, including voltage-dependent activation. HERG is expressed in the heart and is ...
