Abstract excerpt

The eukaryotic chaperonin containing T-complex polypeptide-1 (CCT/TRiC) complex, composed of eight distinct subunits (CCT1-CCT8), is essential for cytosolic protein folding; however, its function in plants remains largely unexplored. Moreover, a direct link between CCT and coat protein complex II (COPII) vesicle trafficking-a key step in the early secretory pathway-has not been established in any eukaryotic...
