CC -!- FUNCTION: Regulatory subunit of the cyclin-dependent kinase pair
CC (CDK9/cyclin T) complex, also called positive transcription elongation
CC factor B (P-TEFb), which is proposed to facilitate the transition from
CC abortive to production elongation by phosphorylating the CTD (carboxy-
CC terminal domain) of the large subunit of RNA polymerase II (RNAP II).
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=a;
CC IsoId=P34425-1; Sequence=Displayed;
CC Name=b;
CC IsoId=P34425-2; Sequence=VSP_015984;
CC Name=c;
CC IsoId=P34425-3; Sequence=VSP_015983;
CC -!- SIMILARITY: Belongs to the cyclin family. Cyclin C subfamily.
CC {ECO:0000305}.
