CC -!- FUNCTION: Atypical chemokine receptor that controls chemokine levels
CC and localization via high-affinity chemokine binding that is uncoupled
CC from classic ligand-driven signal transduction cascades, resulting
CC instead in chemokine sequestration, degradation, or transcytosis. Also
CC known as interceptor (internalizing receptor) or chemokine-scavenging
CC receptor or chemokine decoy receptor. Has a promiscuous chemokine-
CC binding profile, interacting with inflammatory chemokines of both the
CC CXC and the CC subfamilies but not with homeostatic chemokines. Acts as
CC a receptor for chemokines including CCL2, CCL5, CCL7, CCL11, CCL13,
CC CCL14, CCL17, CXCL5, CXCL6, IL8/CXCL8, CXCL11, GRO, RANTES, MCP-1 and
CC TARC. May regulate chemokine bioavailability and, consequently,
CC leukocyte recruitment through two distinct mechanisms: when expressed
CC in endothelial cells, it sustains the abluminal to luminal transcytosis
CC of tissue-derived chemokines and their subsequent presentation to
CC circulating leukocytes; when expressed in erythrocytes, serves as blood
CC reservoir of cognate chemokines but also as a chemokine sink, buffering
CC potential surges in plasma chemokine levels (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Early endosome {ECO:0000250}. Recycling endosome
CC {ECO:0000250}. Membrane; Multi-pass membrane protein.
CC Note=Predominantly localizes to endocytic vesicles, and upon
CC stimulation by the ligand is internalized via caveolae. Once
CC internalized, the ligand dissociates from the receptor, and is targeted
CC to degradation while the receptor is recycled back to the cell membrane
CC (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC Atypical chemokine receptor subfamily. {ECO:0000305}.
