| Outline of Final Research Achievements |
We declared that ERdj5 interacts with SERCA2, which is a Ca2+ uptake pump, through the mixed disulfide bond. It suggests that ERdj5 reductase activity promotes SERCA2 pump function. Recently, we found the oligomer formation of ERdj5 depending on Ca2+ concentration in ER. These oligomer formation regulates the interaction with SERCA2. Additionally, we reported that accumulations of collagen by Hsp47 deficient lead to Cell death through ER stress by Autophagy inhibition. Especially, these cell death links to therapeutic for liver fibrosis (K. Kawasaki, R.Ushioda et al. 2015 J. Biol. Chem.)
