Beschreibung

General description

Regulated on activation, normal T cell expressed and secreted (RANTES), also known as C-C motif chemokine ligand 5 (CCL5), is encoded by the gene mapped to human chromosome 17. RANTES belongs to the chemokine family of proinflammatory basic polypeptides and is expressed by various hematopoietic and non-hematopoietic cell types involved in homing and migration of effector and memory T cells during acute infections.

Biochem/physiol Actions

Regulated on activation, normal T cell expressed and secreted (RANTES) is a chemoattractant towards monocytes, dendritic cells (DCs), memory T cells (CD4⁺/CD45RO), basophils, and eosinophils. The encoded chemokine protein functions as a ligand for CCR1, CCR3, and CCR5. RANTES inhibits the action of R5 strains of HIV-1 via blocking CCR5 receptor. A variant of RANTES gene is linked with susceptibility to HIV-1 infection and disease progression. Hence, this can be used as a potent biomarker to determine the prognosis of HIV -1 infection.

Physical form

Lyophilized from a 0.2 μm filtered solution in 35% acetonitrile and 0.1% trifluoroacetic acid containing 0.5 mg bovine serum albumin.

Analysis Note

The biological activity is tested in culture using Baf/3 cells. Chemotaxis: EC₅₀: 1-5 ng/mL
