Journal: Mol Cell / Year: 2026 Title: NAC promotes co-translational protein folding at the ribosomal tunnel exit. Authors: Jaime Santos / Manuel Günnigmann / Radoslaw J Gora / Marija Iljina / Masa Predin / Ilgin Eser Kotan / Pratiman De / Dhawal Choudhary / Juwon Jang / Frank Tippmann / Christopher Hins / Nenad ...Authors: Jaime Santos / Manuel Günnigmann / Radoslaw J Gora / Marija Iljina / Masa Predin / Ilgin Eser Kotan / Pratiman De / Dhawal Choudhary / Juwon Jang / Frank Tippmann / Christopher Hins / Nenad Ban / Sander J Tans / Shu-Ou Shan / Günter Kramer / Bernd Bukau / Abstract: The nascent polypeptide-associated complex (NAC) coordinates enzymatic modifications and membrane targeting of nascent chains during translation. While the role of NAC as a dynamic hub for other ...The nascent polypeptide-associated complex (NAC) coordinates enzymatic modifications and membrane targeting of nascent chains during translation. While the role of NAC as a dynamic hub for other factors is well established, its direct role in co-translational folding is unclear. By proteome-wide profiling of co-translational NAC interactions in human cells, we found that NAC recognizes emerging segments enriched in hydrophobicity and α-helical propensity within folded domains of cytonuclear proteins. Single-molecule and structural analyses reveal that NAC, via its β-barrel domain, dynamically interacts with nascent chains at the ribosomal tunnel exit and is capable of promoting on-pathway folding. Compartment-specific nascent chain interactions of NAC further elucidate its role in targeting to the endoplasmic reticulum and in mitochondrial membrane protein biogenesis. Together, these findings show that human NAC acts as a bona fide co-translational chaperone that directly promotes early protein folding at the ribosomal tunnel exit, expanding its functional repertoire in protein biogenesis.

In the structure databanks used in Yorodumi, some data are registered as the other names, "COVID-19 virus" and "2019-nCoV". Here are the details of the virus and the list of structure data.
Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)
EMDB accession codes are about to change! (news from PDBe EMDB page)
The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
The EM Navigator/Yorodumi systems omit the EMD- prefix.

Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
