WebJan 4, 2024 · As a result, ATF6-mediated ERS played a role in HCPT-induced fibroblast apoptosis. Autophagy-related proteins and autophagosomes were detected after the HCPT administration using western blot and TEM analyses, respectively. ... (ATF6 p90) dissociates from GRP78/Bip and splits into ATF-6p50 and ATF-6p40, of which the former enters the … WebFeb 21, 2024 · We also found that UPR-related genes, namely BIP, ATF6 and, albeit to a lower extent, CHOP are less expressed in GI compared to NG obese patients. This may be related to the higher amount of BIP protein since BIP buffering capacity on IRE1, PERK and ATF6 may reduce their activation, ...

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. WebFigure S1D. Expression of BiP and GRP94 in H2.35 Cells Overexpressing CREBH or ATF6 H2.35 cells in a 35 mm collagen-coated plate were transfected with 1.5 µg empty DNA vector, vector expressing the nuclear form of CREBH (CREBH-N) or vector expressing the nuclear form of ATF6 (ATF6 p50), respectively. Expression levels of BiP and GRP94 WebDec 27, 2016 · ATF6 is a key regulator of the unfolded protein response. In response to endoplasmic reticulum (ER) stress, ATF6 migrates from the ER to Golgi to undergo regulated intramembrane proteolysis to release a cytosolic domain containing a basic leucine zipper (bZIP) transcriptional activator. dew drop broadheath worcester
