Bip atf4
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. ... (Wang et al., 1996), ATF4 ... WebA similar result was obtained at the mRNA level using reverse transcription polymerase chain reaction (RT-PCR) analyses of BiP, ATF4, XBP1, and CHOP in HeLa cells overexpressing ATE1 1A7A (Fig. 2G and fig.
