Jam2 Gene Summary [Rat]
Predicted to enable integrin binding activity. Predicted to be involved in several processes, including hematopoietic stem cell migration to bone marrow; leukocyte tethering or rolling; and negative regulation of myelination. Predicted to act upstream of or within negative regulation of cell adhesion. Predicted to be located in cell-cell contact zone and somatodendritic compartment. Predicted to be part of protein complex involved in cell adhesion. Predicted to be active in cell surface; plasma membrane; and tight junction. 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 rat 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.
