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) via a RAC1-PAK1- LIMK1 signaling pathway. Activation of this pathway results in up- regulation of ACKR2 from endosomal compartment to cell membrane, increasing its efficacy in chemokine uptake and degradation.

Found in endothelial cells lining afferent lymphatics in dermis and lymph nodes. Also found in lymph nodes subcapsular and medullary sinuses, tonsillar lymphatic sinuses and lymphatics in mucosa and submucosa of small and large intestine and appendix. Also found in some malignant vascular tumors. Expressed at high levels in Kaposi sarcoma-related pathologies. Expressed on apoptotic neutrophils (at protein level). Expressed primarily in placenta and fetal liver, and found at very low levels in the lung and lymph node.
Early endosome. Recycling endosome. Cell membrane; Multi-pass membrane protein. Predominantly localizes to endocytic vesicles, and upon stimulation by the ligand is internalized via clathrin-coated pits. Once internalized, the ligand dissociates from the receptor, and is targeted to degradation while the receptor is recycled back to the cell membrane.
