SEC23-SEC31 the interface plays critical role for export of procollagen from the endoplasmic reticulumSun Don Kim
Section of Genetics, Department of Pediatrics, University of California Davis Medical Center, Sacramento, California 95817, USA
J Biol Chem 287:10134-44. 2012..Our results indicate that a longer stay of COPII proteins on the membrane is required to cargo procollagen than other molecules and suggest that the SEC23-SEC31 interface plays a critical role in capturing various cargo molecules...
