Fractalkine Information: Fractalkine Protein, Fractalkine Antibody and Fractalkine Gene

Fractalkine Gene family

Fractalkine Protein

Fractalkine protein function

Acts as a ligand for both CX3CR1 and integrins. Binds to CX3CR1 (PubMed:23125415, PubMed:9931005, PubMed:21829356). Binds to integrins ITGAV:ITGB3 and ITGA4:ITGB1. Can activate integrins in both a CX3CR1-dependent and CX3CR1-independent manner. In the presence of CX3CR1, activates integrins by binding to the classical ligand-binding site (site 1) in integrins. In the absence of CX3CR1, binds to a second site (site 2) in integrins which is distinct from site 1 and enhances the binding of other integrin ligands to site 1 (PubMed:23125415, PubMed:24789099). The soluble form is chemotactic for T-cells and monocytes and 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 (PubMed:9024663, PubMed:9177350). {ECO:0000269|PubMed:21829356, ECO:0000269|PubMed:23125415, ECO:0000269|PubMed:24789099, ECO:0000269|PubMed:9024663, ECO:0000269|PubMed:9177350, ECO:0000269|PubMed:9931005}.

Fractalkine Gene

CX3CL1 gene / cDNA is a protein-coding gene which located on 16q21. The CX3CL1 gene is conserved in chimpanzee, Rhesus monkey, dog, cow, mouse, and rat.144 organisms have orthologs with human gene CX3CL1.
