Recent reports have shown that Tat can also interact with the multisubunit transcription factor TFIIH complex and increase the phosphorylation of CTD by the Cdk activating kinase (CAK) complex associated with the core TFIIH

The presence of recombinant CTD inhibits in vitro transcription from both the DHFR and adenovirus 2 major late promoters, suggesting that the CTD is involved in essential interactions with a general transcription factor ( s )
