Also known as interceptor (internalizing receptor) or chemokine-scavenging receptor or chemokine decoy receptor. Acts as a receptor for chemokines including CCL2, CCL3, CCL3L1, CCL4, CCL5, CCL7, CCL8, CCL11, CCL13, CCL17, CCL22, CCL23, CCL24, SCYA2/MCP-1, SCY3/MIP-1-alpha, SCYA5/RANTES and SCYA7/MCP-3. Upon active ligand stimulation, activates a beta-arrestin 1 (ARRB1)-dependent, G protein- independent signaling pathway that results in the phosphorylation of the actin-binding protein cofilin (CFL1) through a RAC1-PAK1- LIMK1 signaling pathway. Activation of this pathway results in up- regulation of ACKR2 from endosomal compartment to cell membrane, increasing its efficiency in chemokine uptake and degradation. By scavenging chemokines in tissues, on the surfaces of lymphatic vessels, and in placenta, plays an essential role in the resolution (termination) of the inflammatory response and in the regulation of adaptive immune responses. Plays a major role in the immune silencing of macrophages during the resolution of inflammation. Acts as a regulator of inflammatory leukocyte interactions with lymphatic endothelial cells (LECs) and is required for immature/mature dendritic cells discrimination by LECs. {ECO:0000269|PubMed:23479571, ECO:0000269|PubMed:23633677}. |7tm 1| |chemokine receptor activity| |C-C chemokine receptor activity| |C-C chemokine binding| |chemokine binding| |scavenger receptor activity| |chemokine-mediated signaling pathway| |actin filament| |response to chemokine| |cellular response to chemokine| |recycling endosome| |calcium-mediated signaling| |cell chemotaxis| |nuclear membrane| |early endosome| |positive regulation of cytosolic calcium ion concentration| |regulation of cytosolic calcium ion concentration| |second-messenger-mediated signaling| |external side of plasma membrane| |cellular calcium ion homeostasis| |calcium ion homeostasis| |cellular divalent inorganic cation homeostasis| |divalent inorganic cation homeostasis| |inflammatory response| |chemotaxis| |taxis| |endocytosis| |cellular metal ion homeostasis| |metal ion homeostasis| |cellular cation homeostasis| |cellular ion homeostasis| |cytokine-mediated signaling pathway| |import into cell| |intracellular membrane-bounded organelle| |cation homeostasis| |inorganic ion homeostasis| |cellular chemical homeostasis| |ion homeostasis| |cellular homeostasis| |cell migration| |cellular response to cytokine stimulus| |cell motility| |localization of cell| |response to cytokine| |chemical homeostasis| |locomotion| |G protein-coupled receptor signaling pathway| |defense response| |integral component of plasma membrane| |movement of cell or subcellular component| |homeostatic process| |intracellular signal transduction| |immune response| |vesicle-mediated transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp363|GSK-J4 1-1.25μM to day4 R07 exp363]]|-2.13| No correlation found to any other genes in chemogenomics.
