C-X-C chemokine receptor type 7 (CXCR-7) is a protein that in humans is encoded by the CXCR7 gene.This gene encodes a member of the G protein-coupled receptor family. This protein was earlier thought to be a receptor for vasoactive intestinal peptide (VIP) and was considered to be an orphan receptor. It is now classified as a chemokine receptor able to bind the chemokines CXCL12/SDF-1 and CXCL11. The protein is also a coreceptor for human immunodeficiency viruses (HIV).
