K_v7.2 (KvLQT2) is a potassium channel protein coded for by the gene KCNQ2.

It is associated with benign familial neonatal epilepsy.

Template:PBB Summary

Ligands

ICA-069673: channel opener at KCNQ2/Q3, 20-fold selective over KCNQ3/Q5, no measurable activity against a panel of cardiac ion channels (hERG, Nav1.5, L type channels, and KCNQ1) and no activity on GABA_A gated channels at 10 μM. A range of related benzamides exhibited activity, of which compound number 40 is shown here.^[5]
ML252: channel inhibitor, IC₅₀ = 70nM.^[6]
