Bip atf4
WebThe induction of Bip, ATF4, and CHOP maintained over the course of the experiment, although the magnitude of induction varied at the later time points (24 and 48 h) (Fig. 2A). ATF4 induction was prior to CHOP induction and showed a pattern similar to CHOP, supporting the idea that ATF4 is an upstream transcription factor of CHOP upon ER stress. 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.

WebBiP binding to the lumenal domain of ATF6 retains the protein in the ER compartment. However, under conditions of ER stress, BiP dissociates from ATF6, which then migrates (presumably by vesicular transport) to a post-ER compartment that contains the proteases that liberate the effector domain to signal in the UPR. ...
