Term Name:	gap junction channel activity involved in SA node cell-atrial cardiac muscle cell electrical coupling
Synonyms:	gap junction channel activity involved in SA node cell-atrial cardiomyocyte electrical coupling, gap junction channel activity involved in SAN cell-atrial cardiomyocyte electrical coupling, gap junction channel activity involved in sinoatrial node cell-atrial cardiomyocyte electrical coupling, gap junction channel activity involved in sinus node cell-atrial cardiomyocyte electrical coupling
Definition:	A wide pore channel activity that enables a direct cytoplasmic connection from an SA node cell to an atrial cardiomyocyte. The gap junction passes electrical signals between the cells contributing to cardiac conduction.
