Jam2 Gene Summary [Mouse]
Predicted to enable integrin binding activity. Involved in several processes, including hematopoietic stem cell migration to bone marrow; leukocyte tethering or rolling; and negative regulation of myelination. Acts upstream of or within negative regulation of cell adhesion. Located in cell surface; somatodendritic compartment; and tight junction. Is expressed in several structures, including alimentary system; brain; cardiovascular system; eye; and genitourinary system. Human ortholog(s) of this gene implicated in basal ganglia calcification. Orthologous to human JAM2 (junctional adhesion molecule 2). [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 Jam2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
