Role of the cyclin-dependent kinase 9-related pathway in mammalian gene expression and human diseases
1 Dec 2008
Abstract excerpt
Cyclin-dependent kinase 9 (Cdk9) is a cdc2-like serine/threonine kinase. The so-called Cdk9-related pathway comprises two Cdk9 isoforms (Cdk9-42 and Cdk9-55), cyclin T1, cyclin T2a, cyclin T2b and cyclin K. The association between Cdk9 and one of its cyclin partners forms a heterodimer, which is the main component of the positive transcription elongation factor (P-TEFb). The latter stabilizes the elongation...
