Supplementary information

Cyclin-dependent kinase 7 (Cdk7) also known as CAK is a protein that functions as a serine/threonine kinase. It has a mass of approximately 37 kDa and is expressed in various tissues including the liver heart and testis. Cdk7 forms part of the CDK-activating complex required for the cell cycle's progression and transcription processes. By phosphorylating important sites on target proteins Cdk7 contributes to the regulation of the cell cycle and RNA polymerase II-mediated transcription.
Biological function summary

Cdk7 interacts with other molecules playing a fundamental role in the regulation of cell division and transcription. Cdk7 is a component of the Cdk-activating kinase (CAK) complex alongside cyclin H and MAT1. This complex enables activation of other cyclin-dependent kinases through phosphorylation which is essential for DNA replication and repair. As part of the transcription complex TFIIH Cdk7 enhances RNA polymerase II's transcriptional activity influencing gene expression and cellular responses to external signals.

Pathways

Cdk7 participates in significant regulatory pathways controlling cell cycle and transcription. It is integral to the p53 Signaling and Cell Cycle pathways where it facilitates the activation of CDK1 CDK2 and CDK4/6 key players in cell cycle progression from the G1 to S phase. Through these pathways Cdk7 maintains cellular control upon environmental stress responses and DNA damage providing connections to tumor suppressor proteins such as p53.

Cdk7 has associations with cancer and neurodegenerative diseases. Its dysregulation can lead to unchecked cell proliferation contributing to the development of various cancers like breast and lung cancer. Cdk7's role in transcription implicates it in disorders like Alzheimer's disease where altered transcriptional regulation is observed. Furthermore its interaction with proteins such as p53 links it to cancer as p53 mutations can result in the loss of control over the cell cycle exacerbating tumorigenic processes.

Target data

Serine/threonine kinase involved in cell cycle control and in RNA polymerase II-mediated RNA transcription. Cyclin-dependent kinases (CDKs) are activated by the binding to a cyclin and mediate the progression through the cell cycle. Each different complex controls a specific transition between 2 subsequent phases in the cell cycle. Required for both activation and complex formation of CDK1/cyclin-B during G2-M transition, and for activation of CDK2/cyclins during G1-S transition (but not complex formation). CDK7 is the catalytic subunit of the CDK-activating kinase (CAK) complex. Phosphorylates SPT5/SUPT5H, SF1/NR5A1, POLR2A, p53/TP53, CDK1, CDK2, CDK4, CDK6 and CDK11B/CDK11. CAK activates the cyclin-associated kinases CDK1, CDK2, CDK4 and CDK6 by threonine phosphorylation, thus regulating cell cycle progression. CAK complexed to the core-TFIIH basal transcription factor activates RNA polymerase II by serine phosphorylation of the repetitive C-terminal domain (CTD) of its large subunit (POLR2A), allowing its escape from the promoter and elongation of the transcripts (PubMed : 9852112). Phosphorylation of POLR2A in complex with DNA promotes transcription initiation by triggering dissociation from DNA. Its expression and activity are constant throughout the cell cycle. Upon DNA damage, triggers p53/TP53 activation by phosphorylation, but is inactivated in turn by p53/TP53; this feedback loop may lead to an arrest of the cell cycle and of the transcription, helping in cell recovery, or to apoptosis. Required for DNA-bound peptides-mediated transcription and cellular growth inhibition.
