| Outline of Final Research Achievements |
Thyroid hormone (T3) binds to the thyroid hormone receptor (TR) in the nucleus and exerts hormonal action by regulating the transcriptional activity of the target gene. From the analysis of factors involved in transcriptional regulation of TR, we found that cyclin dependent kinase 9 (CDK9), which is a component of the positive transcriptional elongation factor (P-TEFb) that promotes mRNA synthesis reaction, binds to TR. By recruiting CDK9, TR promotes the transcriptional elongation reaction and enhances the transcriptional activity of the target gene.
