WebApr 7, 2024 · atRAL activates the PERK/eIF2α/ATF4/CHOP signaling pathway of ER stress in 661W photoreceptor cells. A, qRT-PCR analysis of BiP, Atf4 and Chop genes in 661W photoreceptor cells incubated for 6 h with 5-μM atRAL or DMSO (vehicle) alone. The mRNA levels of these genes were shown as fold changes relative to DMSO-treated controls. 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 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. … circulatory system process翻译

WebApr 27, 2015 · The increase in BiP and Atf4 mRNA expression by hypertonic stress in the SON and PVN, suggests that MCNs were responding to a level of ER stress. An increase in BiP mRNA expression in SON and PVN has previously been reported following water deprivation in mice, consistent with our findings here in the rat .

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. ...

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.
