description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables gap junction channel activity involved in bundle of His cell-Purkinje myocyte electrical coupling. Involved in artery morphogenesis; cell communication by electrical coupling involved in cardiac conduction; and regulation of cardiac muscle cell action potential. Acts upstream of or within several processes, including cardiac conduction; circulatory system development; and regulation of systemic arterial blood pressure. Located in gap junction. Is expressed in several structures, including cardiovascular system; cerebral cortex; eye posterior segment; limb mesenchyme; and musculature. Used to study tetralogy of Fallot. Human ortholog(s) of this gene implicated in atrial fibrillation; atrial standstill 1; familial atrial fibrillation; and tetralogy of Fallot. Orthologous to human GJA5 (gap junction protein alpha 5). PHENOTYPE: Homozygotes for targeted null mutations exhibit hypertension, cardiac arrhythmias, reduced atrial and ventricular conduction velocities, and impaired conductance of vasodilation in arterioles of skeletal muscle.
