Summary: 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
