General Information
Term cyclin/CDK positive transcription elongation factor complex ID (Ontology) GO:0008024 (Gene Ontology)
Definition 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 a cyclin and a cyclin-dependent protein kinase catalytic subunit.[ PubMed:10766736 PubMed:16721054 PubMed:17079683 PubMed:19328067 PubMed:7759473 ]
