Chemokine (C-C motif) ligand 5 also known as CCL5 or RANTES is a protein which in humans is encoded by the CCL5 gene.[1]

Function
CCL5 is an 8kDa protein classified as a chemotactic cytokine or chemokine. CCL5 is chemotactic for T cells, eosinophils, and basophils, and plays an active role in recruiting leukocytes into inflammatory sites. With the help of particular cytokines (i.e., IL-2 and IFN-γ) that are released by T cells, CCL5 also induces the proliferation and activation of certain natural-killer (NK) cells to form CHAK (CC-Chemokine-activated killer) cells.[2] It is also an HIV-suppressive factor released from CD8+ T cells. This chemokine has been localized to chromosome 17 in humans.[3]
RANTES was first identified in a search for genes expressed "late" (3–5 days) after T cell activation. It was subsequently determined to be a CC chemokine and expressed in more than 100 human diseases. RANTES expression is regulated in T lymphocytes by Kruppel like factor 13 (KLF13).[4][5][6][7]
History
CCL5 was earlier called Regulated upon Activation, Normal T-cell Expressed, and Secreted, abbreviated RANTES.
