Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables gap junction channel activity involved in AV node cell-bundle of His cell electrical coupling and monoatomic ion channel activity. Involved in negative regulation of cell communication by electrical coupling involved in cardiac conduction and regulation of heart contraction. Located in gap junction. Part of connexin complex. Is expressed in atrioventricular canal; atrioventricular node; and heart. Orthologous to human GJD3 (gap junction protein delta 3).
