| def | "A transcription elongation factor complex that facilitates the transition from abortive to productive elongation by phosphorylating the CTD domain of the large subunit of DNA-directed RNA polymerase II, holoenzyme. Contains cyclin T and a cyclin-dependent protein kinase catalytic subunit." [PMID:10766736, PMID:16721054, PMID:17079683, PMID:19328067, PMID:7759473]
