Molecular Recognition of Cargo by the COPII Complex A Most Accommodating Coat
The molecular mechanism by which diverse cargo proteins are recognized and exported from the ER has been unclear. Two papers in this issue of Cell add clarity by mapping multiple cargo recognition sites in the Sec24 subunit of the COPII coat complex and demonstrating roles for these sites in export of specific protein cargos from the ER.
متن کاملCOPII Coat Composition Is Actively Regulated by Luminal Cargo Maturation
BACKGROUND Export from the ER is an essential process driven by the COPII coat, which forms vesicles at ER exit sites (ERESs) to transport mature secretory proteins to the Golgi. Although the basic mechanism of COPII assembly is known, how COPII machinery is regulated to meet varying cellular secretory demands is unclear. RESULTS Here, we report a specialized COPII system that is actively rec...
متن کاملStructural Mechanism for Cargo Recognition by the Retromer Complex
Retromer is a multi-protein complex that recycles transmembrane cargo from endosomes to the trans-Golgi network and the plasma membrane. Defects in retromer impair various cellular processes and underlie some forms of Alzheimer's disease and Parkinson's disease. Although retromer was discovered over 15 years ago, the mechanisms for cargo recognition and recruitment to endosomes have remained el...
