CX3CR1

Enables C-X3-C chemokine binding activity and C-X3-C chemokine receptor activity. Involved in several processes, including leukocyte migration; nervous system development; and synapse organization. Acts upstream of or within several processes, including macrophage chemotaxis; microglial cell activation involved in immune response; and negative regulation of extrinsic apoptotic signaling pathway in absence of ligand. Located in cell surface. Is expressed in several structures, including colon; genitourinary system; and liver. 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).
