Gjd3 Gene Summary [Mouse]
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). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Gjd3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
