ACKR1 or DARC is an atypical chemokine receptor that controls chemokine levels and localization via high-affinity chemokine binding that is uncoupled from classic ligand-driven signal transduction cascades resulting instead in chemokine sequestration, degradation, or transcytosis. ACKR1 is also known as an interceptor (internalizing receptor) or chemokine-scavenging receptor or chemokine decoy receptor. It has a promiscuous chemokine-binding profile by interacting with inflammatory chemokines of both the CXC and the CC subfamilies but not with homeostatic chemokines. ACKR1 also acts as a receptor for chemokines including CCL2, CCL5, CCL7, CCL11, CCL13, CCL14, CCL17, CXCL5, CXCL6, IL8/CXCL8, CXCL11, GRO, RANTES, MCP-1, TARC and for the malaria parasites P.vivax and P.knowlesi.
