Jag1 - jagged canonical Notch ligand 1

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. Located in plasma membrane. Human ortholog(s) of this gene implicated in Alagille syndrome; congenital heart disease; multiple sclerosis; and tetralogy of Fallot. Orthologous to human JAG1 (jagged canonical Notch ligand 1). [provided by Alliance of Genome Resources, Apr 2022]
