Research Abstract

The structure of wild type SOD1 is thought to be changed by some cellular stress, and induces the endoplasmic reticulum stress through the interaction with Derlin-1, which is the important component of endoplasmic reticulum quality control system. Then, we tried to identify the factor which induces the interaction between wild type SOD1 and Derlin-1. Then, we identified the serum starvation induces the interaction and triggers endoplasmic reticulum stress.
