  • hHCN4 current traces recorded on QPatch™ HT. Onset and block of hHCN4 currents elicited by hyperpolarizing test pulses (duration, 1000 ms; amplitude, -120 mV)-20 mV . Traces in the absence and presence of the blocker zatebradine (10 μM) gave peak current amplitudes of ~1600 nA and ~900 nA, respectively.
  • Concentration-response relationship, IC50 = 13.7 µM. Recording instrument: QPatch HT™.

Quick Overview

Human HCN4 hyperpolarization-gated ion channel-expressing, stable replicating cell line (CHO).

Background

The human HCN4 gene encodes the pore-forming subunit of a hyperpolarization-activated, cyclic nucleotide-modulated cation channel. HCN4 channels are the predominant HCN isoform in the sinoatrial node and contribute to pacemaker current that controls rhythmic activity in the heart and brain. The HCN4 therapeutic potential includes treatment of cardiac arrhythmia and ischemic heart disease.
