The Cdks are serine/threonine protein kinases which are predominantly involved in the progression of the cell cycle. Some CDKs (CDK7, CDK8 and CDK9) participates as part of transcription factors in gene transcription. CDK9 is associated with T- and K-type cyclins and forms a complex with the transcription elongation factor b (P-TEFb). The complex is responsible for phosphorylation of the C-terminal domain of the largest subunit of RNA polymerase II. CDK9 is involved in controlling cell growth, cellular viability and differentiation. Additionally, CDK9 is also critical for HIV-1 and HIV-2 replication in human cells. Deregulation of the CDK9-related pathways are associated with various types of human malignancies and cardiomyocytes hypertrophy.
