  • Tertiapin-Q (TQ) and Ba2+ inhibition of hKir3.1/hKir3.4 recorded by PatchXpress®. Whole-cell currents activated by GTPgS (upper panel), were elicited by voltage step-ramps from ‑120mV to +60 mV from a holding potential of ‑80 mV (lower panel).
  • Concentration-dependence of tertiapin-Q inhibition. The IC50 value was 16.9 nM. Recording instrument: PatchXpress®.

Quick Overview

Human Kir3.1/Kir3.4 potassium ion channel-expressing, stable replicating cell line.

Background

The human KCNJ3 and KCNJ5 genes encode the pore-forming subunits of heteromeric Kir3.1/Kir3.4, an inward rectifier potassium channel. Kir3.1/Kir3.4 channels expressed in heart are linked to M2 muscarinic acetylcholine receptors that mediate vagal inhibitory control of heart rate. Kir3.1/Kir3.4 is a potential target for treatment of atrial fibrillation.
