Abstract:
In this article, we provide a brief summary of work by us and others to discover the molecular underpinnings of early conduction system development and function. We focus on how the multifunctional protein Tbx3 contributes to acquisition and homeostasis of the tissue-specific properties of the sinoatrial and atrioventricular nodes. We also provide unpublished, preliminary findings supporting the role of Tbx3-regulated alternative RNA processing in the developing conduction system.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
