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. WebMar 6, 2024 · ATF6 is the third sensor protein of UPR cascades which is embedded in the ER membrane. By interaction of aggregated proteins with ATF6 in the ER lumen and release of BiP, ATF6 translocates to the Golgi apparatus and undergoes proteolysis.
