WebThe location of the second uORF, aptly named uORF2, overlaps with the ATF4 open-reading frame. During normal conditions, the uORF1 is translated, and then translation of uORF2 occurs only after eIF2-TC has been reacquired. Translation of the uORF2 requires that the ribosomes pass by the ATF4 ORF, whose start codon is located within uORF2. … WebJun 25, 2024 · Interestingly, (+)-grandione (11) induced the HCT-116 cell apoptosis in a dose-dependent manner, which might be attributed to the upregulation of the BiP-ATF4-CHOP axis and promotion of the BiP …

WebAug 18, 2024 · We demonstrated a significant increase in UPR proteins (GRP78 (BiP), ATF4, peIF2 [phosphorylated-eukaryotic initiation factor 2], and CHOP) in dnTCF4-LS174T cells exposed to doxycycline for 48 h (high MUC2 expressing cells) following treatment with combination of orlistat (100 μM) and celecoxib (50 μM) compared to low mucin producing … 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.

However, this treatment also caused mitochondrial dysfunction, including decreased mitochondrial membrane potential, increased mitochondrial reactive oxygen species (ROS) production, and impaired mitochondrial … 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. ...
