Intraperitoneal injection of 4-PBA at 30 minutes before formalin injection inhibits the expression of BIP, ATF6, p-PERK and c ...
WebApr 6, 2012 · The BiP-ATF6 complex formed stably and was purified in all instances. The BiP-IRE1 and BiP-PERK complexes required the addition of ATP to be purified. The T37G mutation in BiP which abolishes an ATP induced conformational change prevented complex purification. BiP binds IRE1 and PERK differently than generic unfolded proteins. WebJan 31, 2024 · The ATF6 pathway is presumably activated during viral infection, as suggested by the proteolytic cleavage of p90ATF6, whereas the production of the active p50ATF6 fragment and the activation of its downstream target gene BiP in an ATF6- and ERSE-dependent manner do not occur . In the present study, we further examined the …
WebSep 24, 2024 · Consistent with prior studies, treatment of HEK293 cells expressing the Class 1 ATF6 disease-associated proteins with the chemical ER stressor, dithiothreitol (DTT), did not induce production of the active ATF6 transcription factor (ATF6 NT) or increase levels of the ATF6 target protein GRP78/BiP (Fig. 4B) . WebATF6 activation by regulated intramembrane proteolysis. Membrane tethering inactivates the transcription factor ATF6, whose effector domain is prevented from accessing its target genes in the nucleus. BiP binding to the lumenal domain of ATF6 retains the protein in the ER compartment.
