Product Specific Information

Antibody detects endogenous levels of CDK9 only when phosphorylated at Ser347.

Target Information

CDK9 is a serine/threonine kinase which when complexed with CyclinT1 forms an active holoenzyme complex. This complex plays a key role in regulating the eukaryotic cell cycle. CDK9 is coexpressed and copurified with CyclinT1. CDK9 regulates cytokine inducible transcription networks by facilitating promoter recognition of target transcription factors. CDK9 promotes RNA synthesis in genetic programs for cell growth, differentiation, and viral pathogenesis. The CDK9/cyclin-K complex also has kinase activity towards CTD of RNAPII and can substitute for CDK9/cyclin-T P-TEFb in vitro. Chronic activation of CDK9 causes cardiac myocyte enlargement leading to cardiac hypertrophy and confers a predisposition to heart failure.
