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}.
