Fig. 3From: The nuclear transportation routes of membrane-bound transcription factorsER membrane-bound proteins relocate in the nucleus by trafficking to the Golgi. (a1-a2) ER membrane-located proteins are transported to the Golgi by COPII vesicles. (a3) Within the Golgi apparatus they are cleaved by Golgi-resident proteases. (a4) Finally, soluble cytosolic segments enter the nucleus to play a transcription regulation roleBack to article page
