NCIt definition : Human CX3CR1 wild-type allele is located in the vicinity of 3p22.2 and is approximately
18 kb in length. This allele, which encodes CX3C chemokine receptor 1 protein, plays
a role in leukocyte endothelial trafficking.;
NCIt note : Up-regulated by chronic inflammation and expressed in brain, peripheral blood leukocytes,
and spleen, the intronless 16.5-kb human CX3CR1 Gene (CCR Family, Rhodopsin Family)
at 3p21.3 produces a 3.2-kb transcript that encodes a seven transmembrane high-affinity
Fractalkine Receptor, a regulator of leukocyte endothelial trafficking: chemotaxis,
cell migration, and adhesion. CX3CR1 signals through a pertussis toxin sensitive G-protein
to induce migration and contains common GPCR features. CX3CR1 may be an HIV envelope
protein co-receptor with CD4.;
