WebTwo Golgi localization signals (GLSs) were identified in ATF6. Removal of BiP binding sites from ATF6, while retaining a GLS, resulted in its constitutive translocation to the Golgi. These results suggest that BiP retains ATF6 in the ER by inhibiting its GLSs and that dissociation of BiP during ER stress allows ATF6 to be transported to the Golgi.

WebMay 20, 2014 · The main originality of the present study is to evidence that supplementation in pomegranate or green tea extracts repressed the increase of BiP, ATF4, XBP1s and XBP1u induced by a HFD. Since BiP is the key chaperone for activating cell response to ER stress [ 38 ], we may conclude that ER stress occurs in skeletal muscle of mice fed with … WebDec 30, 2011 · The activation of ATF4, which is induced by the PERK-mediated phosphorylation of eIF2α, is thought to play a dominant role in the induction of CHOP in response to ER stress . The overexpression of CHOP promotes apoptosis in several cell lines, whereas CHOP-deficient cells are resistant to ER stress-induced apoptosis ( 4 , 7 ).
