Trypanosomal TBP Functions with the Multisubunit Transcription Factor tSNAP To Direct Spliced-Leader RNA Gene Expression
29 Jul 2005
Abstract excerpt
Protein-coding genes of trypanosomes are mainly transcribed polycistronically and cleaved into functional mRNAs in a process that requires trans splicing of a capped 39-nucleotide RNA derived from a short transcript, the spliced-leader (SL) RNA. SL RNA genes are individually transcribed from the only identified trypanosome RNA polymerase II promoter. We have purified and characterized a sequence-specific SL RNA...
