Protein
Fractalkine
Gene
Cx3cl1, Acc1, Fkn, Scyd1
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript leveli

Functioni

The soluble form is chemotactic for T-cells and monocytes, but not for neutrophils. The membrane-bound form promotes adhesion of those leukocytes to endothelial cells. May play a role in regulating leukocyte adhesion and migration processes at the endothelium. Binds to CX3CR1.
