Background Information

Transcription elongation is an key target for control of eukaryotic gene expression. After initiating from a promoter, the RNA polymerase II elongation complex is subjected to a block to elongation by the action of components of N-TEF (negative transcription elongation factor) [PMID: 9748214]. Transcription termination factor 2 (TTF2) is a DsDNA-dependent ATPase that acts as a transcription termination factor by coupling ATP hydrolysis with removal of RNA polymerase II from the DNA template. It also contribute to mitotic transcription repression, and involved in pre-mRNA splicing[PMID:15125840, 12927788].
