The structure of the RT6 mono(ADP-ribosyl)transferase gene was studied. Analysis of cDNA clones revealed eight exons and suggested two independent transcriptional start sites. The existence of the downstream initiation site was confirmed by S1-nuclease protection and localized to position +29 of exon 2. The corresponding 5' flanking regions were found to contain typical promoter structures such as TATA- and CCAAT-boxes. Comparison with sequences deposited in the TRANSFAC database of transcription factor binding sites revealed few putative regulatory elements in the region associated with exon 1 (promoter 1). In contrast, several elements contained in the regulatory regions of other T cell-specific genes, such as ets, lyf-1 and ikaros were found in in promoter 2. Analysis of RT6-transcripts showed this region to be the most active promoter in spleen cells of adult rats. Finally, transient transfection assays with reporter gene constructs showed promoter 2 to mediate T-cell specific transcription.
