CX3CL1 / NTN / Fractalkine蛋白背景綜述
Chemokine (C-X3-C motif) ligand 1 (CX3CL1) is a large cytokine protein containing multiple domains and is the only known member of the CX3C chemokine family. It is also commonly known as fractalkine (in humans) and neurotactin (in mice). The polypeptide structure of CXC3L1 differs from the typical structure of other chemokines. Mature human CX3CL1 consists of a 76 aa residue chemokine domain, a 241 aa residue stalk region containing 17 degenerate mucin-like repeats, a 19 aa residue transmembrane segment and a 37 aa residue cytoplasmic domain. The extracellular domain of human CX3CL1 can be released, possibly by proteolysis at the dibasic cleavage site proximal to the membrane, to generate soluble CX3CL1. Soluble CX3CL1 potently chemoattracts T cells and monocytes, while the cell-bound CX3CL1 promotes strong adhesion of leukocytes to activated endothelial cells where it is primarily expressed. CX3CL1 elicits its adhesive and migratory functions by interacting with the chemokine receptor CX3CR1.
