โœฆ Synopsis

CDK9 is a cdc2-related kinase protein. Previously named PITALRE, this protein is a serine-threonine kinase involved in many physiological processes. Unlike most of the cdc2-like kinases, its activity is not cell cycle-regulated. CDK9 acts preferentially in processes different from cell-cycle regulation, such as differentiation. Its cyclin partners, cyclins of T family, recently have been isolated. CDK9 immunoprecipitates with several unidentified polypeptides that may regulate its kinase activity. CDK9 has been shown to associate with the HIV-Tat protein, suggesting a possible involvement in AIDS. CDK9 recently was shown to be responsible for the kinase activity associated with the TAK complex and with the P-TEFb complex, suggesting activity also in the transcription process.

Mammalian cell cycle progression is regulated by sequential activation and inactivation of cyclin-dependent kinases (cdks). Recently, several new members of the cdk family were cloned, and some of these were shown to complex with different cyclins and to be active at discrete stages of the cell cycl
