Proteins that are misfolded in the endoplasmic reticulum are transported back into the cytosol for destruction by the proteasome. This retro-translocation pathway has been co-opted by certain viruses, and by plant and bacterial toxins. The mechanism of retro-translocation is still mysterious, but several aspects of this process are now being unravelled.
在内质网中错误折叠的蛋白质会被转运回细胞质,由蛋白酶体进行降解。某些病毒、植物毒素和细菌毒素利用了这种逆向转运途径。逆向转运的机制仍然神秘,但这一过程的几个方面现在正在被揭示。
