CX3CR1, NT, Blocking Peptide (Fractalkine Receptor, V28, CMKBRL1), Purified

Peptide corresponding to aa2-21 of human CX3CR1 (1). The sequence differs from those of mouse and rat CX3CR1 by four amino acids (3,4). CX3CR1 is one of the chemokine receptors that is required as a coreceptor for HIV infection. The genes encoding human, murine, and rat CX3CR1 were cloned and designated V28 and CMKBRL1, CX3CR1, and RBS11, respectively, (1-4). The encoded seven transmembrane proteins were recently identified as the receptors for a novel transmembrane molecule, fractalkine, and renamed CX3CR1 (5). Recently, CX3CR1 was found to serve as a coreceptor for HIV-1 and HIV-2 envelope fusion and virus infection, which can be inhibited by fractokine (6). CX3CR1 mediates leukocyte migration and adhesion (5). CX3CR1 is expressed in a variety of human tissues and cell lines (2).
