Target description

Atypical chemokine receptor 3 (UniProt: P25106; also known as C-X-C chemokine receptor type 7, CXC-R7, CXCR-7, Chemokine orphan receptor 1, G-protein coupled receptor 159, G-protein coupled receptor RDC1 homolog, RDC-1) is encoded by the ACKR3 (also known as CMKOR1, CXCR7, GPR159, RDC1) gene (Gene ID: 57007) in human. CXCR7 is a multi-pass membrane protein with four extracellular domains, seven transmembrane domains, and four cytoplasmic domains. It predominantly localized to endocytic vesicles and upon stimulation by the ligand internalizes via clathrin-coated pits in a β-arrestin-dependent manner. Once internalized, the ligand dissociates from the receptor and is targeted for degradation while the receptor is recycled back to the cell membrane. CXCR7 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. It is also reported to act as a chemokine-scavenging receptor or chemokine decoy receptor. It acts a as a receptor for chemokines CXCL11 and CXCL12/SDF1. Chemokine binding to CXCR7 does not activate G-protein-mediated signal transduction but instead induces β-arrestin recruitment, leading to ligand internalization and activation of MAPK signaling pathway. In glioma cells, it is reported to transduce signals via MEK/ERK pathway, mediating resistance to apoptosis and promote cell growth and survival. In normal hematopoietic progenitors it is not involved in cell migration, adhesion, or proliferation. However, in malignant cells, its activation by CXCL11 leads to ERK1/2 phosphorylation that causes enhanced cell adhesion and migration. (Ref.: Wang, C., et al. (2018). Front.
