A Traditional Chinese Medicine botanical drug exerts a competitive antagonism on the cAMP-induced modulation of sinoatrial node pacemaker channels and this functional inhibition reduces the slope of the diastolic depolarization hence spontaneous cell automaticity.
The non-selective Na+ leak channel (NALCN) and the transient receptor potential 3 channel (TRPC3) cooperate in driving pacemaking in substantia nigra dopaminergic neurons.
The hyperpolarization-activated inward current plays an important role in regulating both smooth transitory responses and persistent increases in pyloric frequency during temperature fluctuations in Cancer borealis.

An optogenetic dual-color Ca2+-imaging approach shows how submucosal pacemaker-cells, interstitial cells of Cajal, modulate smooth-muscle responses and drive colonic motility via complex Ca2+ signaling.
Dnajb6 is identified as a novel sick sinus syndrome causative gene that exhibits a unique expression pattern within a subpopulation of sinus node pacemaker cells.

Kinetic interactions between sodium channels and auxiliary factors create a molecular computational engine that can sense and regulate cellular excitability.
