Research Abstract |
Nrf2 plays an important role in oxidative stress response in animals. On the other hand, yeast GCN1 plays an essential role in amino acid starvation response. In this study, we found that GCN1L1, a human homologue of GCN1, directly binds to Nrf2 and that GCN1L1 knockdown diminishes Nrf2 response in various human cancer cells and mouse fibroblasts. Furthermore, Nrf2 was activated by the amino acid starvation. These results suggest the cross talk of Nrf2 stress response with amino acid starvation response pathway.
