Chemokine receptors and ligands
Did you know?
WebChemokine receptors are a group of ∼20 rhodopsin-like seven-transmembrane-spanning receptors in humans and mice ( Table 2 ). These receptors are G-protein-coupled and signal via pertussis toxin-sensitive Gi-type G proteins. The chemokine receptors show varying levels of binding specificity and promiscuity. WebCC chemokine receptors (or beta chemokine receptors) are integral membrane proteins that specifically bind and respond to cytokines of the CC chemokine family.
WebFollowing interaction with their specific chemokine ligands, chemokine receptors trigger a flux in intracellular calcium (Ca2+) ions (calcium signaling). This causes cell responses, including the onset of a process known as chemotaxis that traffics the cell to a desired location within the organism. Figure 2.
