WebTwo Golgi localization signals (GLSs) were identified in ATF6. Removal of BiP binding sites from ATF6, while retaining a GLS, resulted in its constitutive translocation to the Golgi. These results suggest that BiP retains ATF6 in the ER by inhibiting its GLSs and that dissociation of BiP during ER stress allows ATF6 to be transported to the Golgi.
