The chemotactic cytokine RANTES (Regulated on Activation, Normal T-cell Expressed and Secreted) is a potent chemoattractant and activator of a number of leukocytes, with a molecular mass of 8 kDa. Crystals of this protein have been grown from 100 mM sodium acetate buffer (pH 4.6) containing 200 mM magnesium acetate, with 20% (w/v) PEG 4000 and 6% (v/v) glycerol. The crystals grow as thick rods, which diffract to at least 1.8 A resolution on a rotating anode X-ray source. The crystals belong to space group p2(1)2(1)2(1) with unit cell dimensions a = 95.14 A, b = 57.58 A and c = 24.01 A with alpha = beta = gamma = 90 degrees. The asymmetric unit contains two molecules of the RANTES monomer, with a VM of 2.0 A(3)/Da.

D014961 X-Ray Diffraction The scattering of x-rays by matter, especially crystals, with accompanying variation in intensity due to interference effects. Analysis of the crystal structure of materials is performed by passing x-rays through them and registering the diffraction image of the rays (CRYSTALLOGRAPHY, X-RAY).

D018946 Chemokine CCL5 A CC-type chemokine that is a chemoattractant for EOSINOPHILS; MONOCYTES; and LYMPHOCYTES. It is a potent and selective eosinophil chemotaxin that is stored in and released from PLATELETS and activated T-LYMPHOCYTES. Chemokine CCL5 is specific for CCR1 RECEPTORS; CCR3 RECEPTORS; and CCR5 RECEPTORS. The acronym RANTES refers to Regulated on Activation, Normal T Expressed and Secreted.
