| Research Abstract |
I identified β-TrCP and CK2 as Nrf1-binding proteins. I found that β-TrCP regulates Nrf1 degradation in the nucleus and its transcriptional activity(Tsuchiya et al.(2011) Mol. Cell. Biol. 31 : 4500-4512). I also found that CK2 phosphorylates Nrf1 and suppresses its transcriptional activity, thereby impairs Nrf1-dependent induction of proteasome gene expression. These results suggest that phosphorylation of Nrf1 is a novel therapeutic target for ameliorating accumulation of protein aggregates observed in steatohepatitis and neurodegenerative diseases.
