Upon administration, USL311 binds to CXCR4, thereby preventing the binding of stromal-cell derived factor-1 (SDF-1 or CXCL12) to CXCR4 and inhibiting CXCR4 activation, which may result in decreased proliferation and migration of CXCR4-expressing tumor cells. CXCR4, a chemokine receptor belonging to the G protein-coupled receptor (GPCR) family, plays an important role in chemotaxis and angiogenesis, and is upregulated in several tumor cell types."}]
