Outline of Final Research Achievements |
Protein-encoding genes and non-coding RNA genes are transcribed by RNA polymerase II (Pol II). We have found that the human Mediator subunit Med26 uses two different transcription elongation complexes, Super elongation complex (SEC) and Little elongation complex (LEC), to regulate different types of genes by Pol II. In this study, we found that Med26 and SEC regulate the transcription of mRNA with poly A, while Med26 and LEC regulate the transcription of genes without poly A.

Academic Significance and Societal Importance of the Research Achievements |
本研究で、Med26がSECとLECを使い分けることによって転写開始後のプロセス(転写伸長、転写終結)を制御し、mRNAのポリA付加を決定していることが明らかとなれば、遺伝子発現制御の研究分野においてブレークスルーの1つとなることが期待できる。また、Med26はがんや白血病などの腫瘍性疾患の原因となっていることも予想され、本研究による将来の臨床医学への貢献も期待できる。
