CX3CR1: Proteins and Enzymes

Chemokine receptors are seven-transmembrane domain G-protein coupled receptors that mediate the biological activities of chemokines. Most of these receptors exhibit promiscuous binding properties whereby several different chemokines signal through the same receptor. They are named according to the chemokine subfamily they bind. There is currently one CX3C receptor, CX3CR1, the receptor for fractalkine.
