A dual function for chaperones SSB–RAC and the NAC nascent polypeptide–associated complex on ribosomes
The yeast Hsp70/40 system SSB-RAC (stress 70 B-ribosome-associated complex) binds to ribosomes and contacts nascent polypeptides to assist cotranslational folding. In this study, we demonstrate that nascent polypeptide-associated complex (NAC), another ribosome-tethered system, is functionally connected to SSB-RAC and the cytosolic Hsp70 network. Simultaneous deletions of genes encoding NAC and...
متن کاملDual binding mode of the Nascent Polypeptide-associated Complex (NAC) reveals a novel universal adapter site on the ribosome
Nascent Polypeptide-associated Complex (NAC) was identified in eukaryotes as the first cytosolic factor which contacts the nascent polypeptide chain emerging from the ribosome. NAC is present as a homodimer in Archaea and as a highly conserved heterodimer in eukaryotes. Mutations in NAC cause severe embryonically lethal phenotypes in mice, D. melanogaster and C. elegans. In the yeast Saccharomy...
متن کاملSRP and NAC: Guiding a Nascent Protein’s First Steps
A newly synthesized protein is not ready to start working in a cell immediately after it is made by the ribosome. Instead, these nascent proteins must first fold into their proper 3-D shape, and possibly also receive modifications such as the addition of sugars or lipids. The site where these maturation steps take place depends upon where the final protein will be used in the cell: cytosolic pr...

15 صفحه اولRibosome association and stability of the nascent polypeptide-associated complex is dependent upon its own ubiquitination.
In this work we addressed the role of ubiquitination in the function of the nascent polypeptide-associated complex (NAC), named EGD in the yeast Saccharomyces cerevisiae. To this end, we first identified the lysines residues required for ubiquitination of EGD/NAC. While simultaneous mutation of many lysines in the alpha-subunit of NAC (Egd2p) was required to abolish its ubiquitination, for the ...
