Gja4 Gene Summary [Rat]
Predicted to enable gap junction channel activity. Involved in several processes, including calcium ion transport; endothelium development; and response to pain. Located in gap junction. Part of connexin complex. Biomarker of ureteral obstruction. Human ortholog(s) of this gene implicated in coronary artery disease and myocardial infarction. Orthologous to human GJA4 (gap junction protein alpha 4). [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 rat Gja4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
