Jag1 Gene Summary [Rat]
Enables Notch binding activity and receptor ligand activity. Involved in several processes, including animal organ regeneration; inner ear auditory receptor cell differentiation; and positive regulation of cardiac epithelial to mesenchymal transition. Predicted to be located in adherens junction and apical plasma membrane. Biomarker of pulmonary fibrosis. Human ortholog(s) of this gene implicated in Alagille syndrome; Charcot-Marie-Tooth disease; congenital heart disease; multiple sclerosis; and tetralogy of Fallot. Orthologous to human JAG1 (jagged canonical Notch ligand 1). [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 Jag1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
