In eukaryotic cells, nascent membrane or secretory proteins are translocated into the endoplasmic reticulum through the Sec61p translocation channel; recent evidence suggests that, if they fail to achieve a native conformation, they are translocated back into the cytosol by the same route and degraded by the proteasome.
在真核细胞中,新生的膜蛋白或分泌蛋白通过Sec61p转运通道转运到内质网中;最近的证据表明,如果它们未能形成天然构象,就会通过相同途径转运回细胞质,并被蛋白酶体降解。
