WebOne of the well-characterized ER retention factors, BiP, contains multiple binding sites on ATF6α, including two potential Golgi localization sequences ( 15, 19 ). Early events during ER stress cause BiP to be released from ATF6, allowing it to package into COPII vesicles. 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.
