GATA-6 gene enhancer contains nested regulatory modules for primary myocardium and the embedded nascent atrioventricular conduction system.


The cGATA-6 gene is flanked by an enhancer that selectively marks the atrioventricular conduction system (AVCS) in transgenic mice. This enhancer reads anterior/posterior and medial/lateral positional information very early in the cardiogenic program and remains active in progressively more restricted regions of primary myocardium leading up to the… (More)
