Function: Regulatory 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) (PubMed:9499409, PubMed:15563843). The activity of this complex is regulated by binding with 7SK snRNA (PubMed:11713533). Plays a role during muscle differentiation; P-TEFB complex interacts with MYOD1; this tripartite complex promotes the transcriptional activity of MYOD1 through its CDK9-mediated phosphorylation and binds the chromatin of promoters and enhancers of muscle-specific genes; this event correlates with hyperphosphorylation of the CTD domain of RNA pol II (By similarity). In addition, enhances MYOD1-dependent transcription through interaction with PKN1 (PubMed:16331689). Involved in early embryo development (By similarity).
Subunit Structure: Interacts with CDK9 to form P-TEFb (PubMed:9499409, PubMed:16331689). Interacts with POLR2A (via the C-terminal domain (CTD)); mediates transcriptional activity (PubMed:15563843). Interacts with HEXIM1; mediates formation of a tripartite complex with KPNA2. Interacts with HEXIM2 (PubMed:19883659). Interacts with PKN1; enhances MYOD1-dependent transcription (PubMed:16331689). P-TEFB complex interacts with RB1; promotes phosphorylation of RB1 (PubMed:12037672). P-TEFB complex interacts with MYOD1; promotes the transcriptional activity of MYOD1 through its CDK9-mediated phosphorylation (By similarity). Interacts with MDFI and MDFIC (PubMed:17289077). Interacts with MON1B; downregulates CCNT2-mediated activation of viral promoters during herpes simplex virus 1/HHV-1 infection (PubMed:21509660).
Similarity: Belongs to the cyclin family. Cyclin C subfamily.

The protein encoded by this gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. This cyclin and its kinase partner CDK9 were found to be subunits of the transcription elongation factor p-TEFb. The p-TEFb complex containing this cyclin was reported to interact with, and act as a negative regulator of human immunodeficiency virus type 1 (HIV-1) Tat protein. A pseudogene of this gene is found on chromosome 1. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Dec 2010]
