CC -!- FUNCTION: Regulatory subunit of the cyclin-dependent kinase pair
CC (CDK9/cyclin-T1) complex, also called positive transcription elongation
CC factor B (P-TEFb), which is proposed to facilitate the transition from
CC abortive to productive elongation by phosphorylating the CTD (C-
CC terminal domain) of the large subunit of RNA polymerase II (RNA Pol
CC II). {ECO:0000250}.
CC -!- SUBUNIT: Cyclin-T1 is the predominant cyclin that associates with CDK9
CC to form a heterodimer called P-TEFb. P-TEFb forms a complex with
CC AFF4/AF5Q31. Component of a complex which is at least composed of
CC HTATSF1/Tat-SF1, P-TEFb complex, RNA pol II, SUPT5H, and NCL/nucleolin.
CC Component of the 7SK snRNP complex at least composed of P-TEFb
CC (composed of CDK9 and CCNT1/cyclin-T1), HEXIM1, HEXIM2, BCDIN3, SART3
CC proteins and 7SK and U6 snRNAs. Interacts with BRD4, targets chromatin
CC binding. Interacts with JMJD6. Interacts with MDFIC. Interacts with
CC HSF1. Interacts with HTATSF1. Interacts with AFF4. Interacts with
CC TBX21. {ECO:0000250|UniProtKB:O60563}.
CC -!- SUBUNIT: (Microbial infection) Binds to BIV Tat, however Tat binds TAR
CC RNA in a Cyc-T1-independent mode. {ECO:0000269|PubMed:14972556}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the cyclin family. Cyclin C subfamily.
CC {ECO:0000305}.
