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.

WebThe expressions of Bip, Xbp-1, Atf4, and Atf6 mRNAs in the liver were examined to clarify the involvement of UPR in the pathological changes in the liver. The levels of Bip mRNA in the liver in the MIA/P20 group at 2 h (p < 0.05) and 24 h (p < 0.05) were significantly lower than those in the S/P20 group . 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.
