Subunit of positive elongation transcription factor b
FunctionRegulatory subunit of the cyclin-dependent kinase pair (CDK9/cyclin T) complex, also called positive transcription elongation factor B (P-TEFB), which is proposed to facilitate the transition from abortive to production elongation by phosphorylating the CTD (carboxy-terminal domain) of the large subunit of RNA polymerase II (RNAP II).
Tissue specificityUbiquitously expressed.
Sequence similaritiesBelongs to the cyclin family. Cyclin C subfamily.
