Research Abstract

We discovered that unfolded proteins accumulate in the endoplasmic reticulum (ER) of the notochord during medaka early embryonic development, that medaka refolds the accumulated unfolded proteins by activating sensor proteins designated ATF6α and ATF6β and thereby inducing ER-localized molecular chaperones, and that medaka deficient in both ATF6α and ATF β dies due to notochord abnormality. Thus, the unfolded protein response plays a critical role in the homeostasis of the cell and body.
