Biochem/physiol Actions

CXCR4 is a cell surface receptor of the chemokine CXCL12 (SDF-1) and is involved in metastasis, hematopoiesis and immune responses. It acts with CD4 to facilitate the entry of HIV into target cells. CXCR4 has important roles in tumor initiation, proliferation, invasion and metastasis of breast cancer cells.
