Function

Protein kinase involved in the regulation of transcription (PubMed:10574912, PubMed:10757782, PubMed:11145967, PubMed:11575923, PubMed:11809800, PubMed:11884399, PubMed:14701750, PubMed:16109376, PubMed:16109377, PubMed:20930849, PubMed:28426094, PubMed:29335245). Member of the cyclin-dependent kinase pair (CDK9/cyclin-T) complex, also called positive transcription elongation factor b (P-TEFb), which facilitates the transition from abortive to productive elongation by phosphorylating the CTD (C-terminal domain) of the large subunit of RNA polymerase II (RNAP II) POLR2A, SUPT5H and RDBP (PubMed:10574912, PubMed:10757782, PubMed:11145967, PubMed:11575923, PubMed:11809800, PubMed:11884399, PubMed:14701750, PubMed:16109376, PubMed:16109377, PubMed:20930849, PubMed:28426094, PubMed:30134174). This complex is inactive when in the 7SK snRNP complex form (PubMed:10574912, PubMed:10757782, PubMed:11145967, PubMed:11575923, PubMed:11809800, PubMed:11884399, PubMed:14701750, PubMed:16109376, PubMed:16109377, PubMed:20930849, PubMed:28426094). Phosphorylates EP300, MYOD1, RPB1/POLR2A and AR and the negative elongation factors DSIF and NELFE (PubMed:10912001, PubMed:11112772, PubMed:12037670, PubMed:20081228, PubMed:20980437, PubMed:21127351, PubMed:9857195). Regulates cytokine inducible transcription networks by facilitating promoter recognition of target transcription factors (e.g. TNF-inducible RELA/p65 activation and IL-6-inducible STAT3 signaling) (PubMed:17956865, PubMed:18362169). Promotes RNA synthesis in genetic programs for cell growth, differentiation and viral pathogenesis (PubMed:10393184, PubMed:11112772). P-TEFb is also involved in cotranscriptional histone modification, mRNA processing and mRNA export (PubMed:15564463, PubMed:19575011, PubMed:19844166). Modulates a complex network of chromatin modifications including histone H2B monoubiquitination (H2Bub1), H3 lysine 4 trimethylation (H3K4me3) and H3K36me3; integrates phosphorylation during transcription with chromatin modifications to control co-transcriptional histone mRNA processing (PubMed:15564463, PubMed:19575011, PubMed:19844166). The CDK9/cyclin-K complex has also a kinase activity towards CTD of RNAP II and can substitute for CDK9/cyclin-T P-TEFb in vitro (PubMed:21127351). Replication stress response protein; the CDK9/cyclin-K complex is required for genome integrity maintenance, by promoting cell cycle recovery from replication arrest and limiting single-stranded DNA amount in response to replication stress, thus reducing the breakdown of stalled replication forks and avoiding DNA damage (PubMed:20493174). In addition, probable function in DNA repair of isoform 2 via interaction with KU70/XRCC6 (PubMed:20493174). Promotes cardiac myocyte enlargement (PubMed:20081228). RPB1/POLR2A phosphorylation on 'Ser-2' in CTD activates transcription (PubMed:21127351). AR phosphorylation modulates AR transcription factor promoter selectivity and cell growth. DSIF and NELF phosphorylation promotes transcription by inhibiting their negative effect (PubMed:10912001, PubMed:11112772, PubMed:9857195). The phosphorylation of MYOD1 enhances its transcriptional activity and thus promotes muscle differentiation (PubMed:12037670). Catalyzes phosphorylation of KAT5, promoting KAT5 recruitment to chromatin and histone acetyltransferase activity (PubMed:29335245).

Activity summary

Cyclin-dependent kinase 9 (Cdk9) is a serine/threonine protein kinase involved in regulating transcription elongation. It is often referred to as part of the positive transcription elongation factor b (P-TEFb) complex. Cdk9 partners with cyclin T1 T2 or K to form this complex allowing it to phosphorylate the carboxyl-terminal domain (CTD) of RNA polymerase II. The molecular weight of Cdk9 is around 42 kDa. This protein is ubiquitously expressed found in many tissues including the heart liver and brain reflecting its important role.

Biological function summary

Cdk9 functions as a central component of transcriptional processes. It is essential for the transition of RNA polymerase II from the initiation phase to productive elongation. As part of the P-TEFb complex Cdk9 targets negative elongation factors helping relieve their inhibition. This regulation is especially important in the control of genes with strong promoter proximally paused polymerase. By doing so Cdk9 controls the expression of several genes involved in cell growth differentiation and response to stress.

Pathways

Cdk9 plays a significant role in transcription and signal transduction pathways. One important pathway is the NF-κB signaling where Cdk9 regulates the transcription of NF-κB target genes involved in immune response. Another significant pathway is the heat shock response where Cdk9 enhances the expression of heat shock proteins helping cells deal with stress. In both pathways it cooperates with other proteins like cyclins and negative elongation factors illustrating its interconnected role in cellular function.

Associated diseases and disorders

Cdk9 has been linked to several conditions most notably cancer and cardiac hypertrophy. Its overactivation can lead to increased transcription of genes involved in proliferation making it a focus for cancer research. Cdk9 is also implicated in cardiac hypertrophy where its activity affects gene expression that can exacerbate the condition. Researchers study its interaction with other proteins such as THZ1 a Cdk9 inhibitor to explore potential therapeutic avenues.
