The RANTES/CCL5 gene spans ~7.1 kb, is composed of 3 exons (133, 112, and 1075 bases) and 2 introns, with conserved intron/exon boundaries relative to other CC chemokines. The ~1 kb promoter contains consensus elements for T cell/hematopoietic, myeloid, and ubiquitous transcription factors; promoter activity is cell-type specific (high in mature T cells and erythroleukemic cells, absent in early T cell lines). |
