CXC chemokine receptor type 4 (CXCR4) is specific for Stromal Derived Factor 1 (SDF-1α, known also as CXCL12). The CXRC4 is used by HIV to infect CD4+ T cells. The biological unit probably is a [1]. This image based on 3oe0. CXCR1 recognizes CXC chemokines with ELR amino acids adjacent to the CXC motif.
