Full Description	The sorting of proteins to the appropriate compartment is one of the most fundamental cellular processes. We found that in the model organism Caenorhabditis elegans, correct cotranslational endoplasmic reticulum (ER) transport required the suppressor activity of the nascent polypeptide-associated complex (NAC). NAC did not affect the accurate targeting of ribosomes to ER translocons mediated by the signal recognition particle (SRP) pathway but inhibited additional unspecific contacts between ribosomes and translocons by blocking their autonomous binding affinity. NAC depletion shortened the life span of Caenorhabditis elegans, caused global mistargeting of translating ribosomes to the ER, and provoked incorrect import of mitochondrial proteins into the ER lumen, resulting in a strong impairment of protein homeostasis in both compartments. Thus, the antagonistic targeting activity of NAC is important in vivo to preserve the robustness and specificity of cellular protein-sorting routes.
