Jag2 Gene Summary [Mouse]
Enables Notch binding activity. Involved in auditory receptor cell fate commitment; gamma-delta T cell differentiation; and positive regulation of Notch signaling pathway. Acts upstream of or within several processes, including epithelial cell apoptotic process involved in palatal shelf morphogenesis; odontogenesis of dentin-containing tooth; and respiratory system process. Located in plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; sensory organ; and surface ectoderm. Human ortholog(s) of this gene implicated in autosomal recessive limb-girdle muscular dystrophy. Orthologous to human JAG2 (jagged canonical Notch ligand 2).

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 Jag2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
