Title: Cryo-EM structure of the Rev1-Polζ holocomplex reveals the mechanism of their cooperativity in translesion DNA synthesis.

To elucidate the mechanism by which the two polymerases cooperate in TLS, we determined the ...Rev1-Polζ-dependent translesion synthesis (TLS) of DNA is crucial for maintaining genome integrity. To elucidate the mechanism by which the two polymerases cooperate in TLS, we determined the cryogenic electron microscopic structure of the Saccharomyces cerevisiae Rev1-Polζ holocomplex in the act of DNA synthesis (3.53 Å). We discovered that a composite N-helix-BRCT module in Rev1 is the keystone of Rev1-Polζ cooperativity, interacting directly with the DNA template-primer and with the Rev3 catalytic subunit of Polζ. The module is positioned akin to the polymerase-associated domain in Y-family TLS polymerases and is set ideally to interact with PCNA. We delineate the full extent of interactions that the carboxy-terminal domain of Rev1 makes with Polζ and identify potential new druggable sites to suppress chemoresistance from first-line chemotherapeutics. Collectively, our results provide fundamental new insights into the mechanism of cooperativity between Rev1 and Polζ in TLS.

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.

Thousand views of thousand structures

  • 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.
