CYCLIN-DEPENDENT KINASE 9 (CDK9) REGULATION OF MCL-1
The cyclin-dependent kinase (CDK) family of proteins perform important functions in transcription regulation or cell-cycle control.1
CDK9 plays a critical role in transcription regulation2 and does not directly affect cell-cycle control.3 CDK9-mediated transcriptional regulation of anti-apoptotic proteins, such as MCL-1, is critical for the survival of MCL-1—dependent AML* blasts.2
Watch this video to learn more about MCL-1 as an apoptosis inhibitor and what this could mean for MCL-1—dependent AML.
*The prevalence of MCL-1—dependent AML is under investigation.
