Cx3cr1 Gene Summary [Mouse]
Enables C-X3-C chemokine binding activity and C-X3-C chemokine receptor activity. Involved in several processes, including antifungal innate immune response; central nervous system development; and synapse organization. Located in cell surface. Is expressed in several structures, including brain; colon; genitourinary system; head mesenchyme; and meninges. Used to study age related macular degeneration 12. Human ortholog(s) of this gene implicated in several diseases, including human immunodeficiency virus infectious disease; obesity; pulmonary hypertension; retinal disease (multiple); and systemic scleroderma. Orthologous to human CX3CR1 (C-X3-C motif chemokine receptor 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 mouse Cx3cr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
