Different mechanisms of recognition and ER retention by transmembrane transcription factors CREB-H and ATF6.

Abstract excerpt

CREB-H and activating transcription factor 6 (ATF6) are transmembrane transcription factors that, in response to endoplasmic reticulum (ER) stress, traffic to the Golgi where they are cleaved by specific proteases, producing the N-terminal domains that effect appropriate transcriptional responses. We show that unlike in ATF6 whose lumenal tail binds BiP and contains determinants for stress sensing and Golgi...
