The POTRA domains of Toc75 exhibit chaperone-like function to facilitate import into chloroplasts [Plant Biology]

Protein trafficking across membranes is an essential function in cells; however, the exact mechanism for how this occurs is not well understood. In the endosymbionts, mitochondria and chloroplasts, the vast majority of proteins are synthesized in the cytoplasm as preproteins and then imported into the organelles via specialized machineries.
