Function

[CCL5_HUMAN] Chemoattractant for blood monocytes, memory T-helper cells and eosinophils. Causes the release of histamine from basophils and activates eosinophils. Binds to CCR1, CCR3, CCR4 and CCR5. One of the major HIV-suppressive factors produced by CD8+ T-cells. Recombinant RANTES protein induces a dose-dependent inhibition of different strains of HIV-1, HIV-2, and simian immunodeficiency virus (SIV). The processed form RANTES(3-68) acts as a natural chemotaxis inhibitor and is a more potent inhibitor of HIV-1-infection. The second processed form RANTES(4-68) exhibits reduced chemotactic and HIV-suppressive activity compared with RANTES(1-68) and RANTES(3-68) and is generated by an unidentified enzyme associated with monocytes and neutrophils.^[1] ^[2] ^[3] ^[4] ^[5]

Publication Abstract from PubMed

The solution structure of the chemokine RANTES (regulated on activation, normal T-cell expressed and secreted) has been determined using NMR spectroscopy. Backbone and side-chain 1H and 15N assignments have been obtained using a combination of two-dimensional homonuclear and three-dimensional heteronuclear spectra. Regular elements of secondary structure have been identified on the basis of a qualitative interpretation of NOE data, J(NH-H alpha) coupling constants, and amide exchange rates. Three-dimensional structures were calculated from a total of 2146 experimental restraints using a combination of distance geometry and simulated annealing protocols. For the 13 best structures the average backbone (N, C alpha, C) atomic rmsd from the mean coordinates for residues 5-65 is 0.64 A (+/- 0.14 A) for the dimer and 0.50 A (+/- 0.08 A) for the individual monomers. Each monomer consists of a three-stranded antiparallel beta-sheet (residues 26-30, 38-43, 48-51) in a Greek key motif with a C-terminal helix (56-65) packed across the sheet, an arrangement similar to the monomeric structure of other members of this chemokine family (IL-8, PF4, MGSA/Gro alpha, and MIP-1 beta). Overall, the RANTES dimer resembles that previously reported for MIP-1 beta.
