Title: Structures of 9-1-1 DNA checkpoint clamp loading at gaps from start to finish and ramification to biology.

Abstract: Recent structural studies show the Rad24-RFC loads the 9-1-1 checkpoint clamp onto a recessed 5' end by binding the 5' DNA on Rad24 at an external surface site and threading the 3' ssDNA into the ...Recent structural studies show the Rad24-RFC loads the 9-1-1 checkpoint clamp onto a recessed 5' end by binding the 5' DNA on Rad24 at an external surface site and threading the 3' ssDNA into the well-established internal chamber and into 9-1-1. We find here that Rad24-RFC loads 9-1-1 onto DNA gaps in preference to a recessed 5' DNA end, thus presumably leaving 9-1-1 on a 3' ss/ds DNA after Rad24-RFC ejects from the 5' gap end and may explain reports of 9-1-1 directly functioning in DNA repair with various TLS polymerases, in addition to signaling the ATR kinase. To gain a deeper understanding of 9-1-1 loading at gaps we report high-resolution structures of Rad24-RFC during loading of 9-1-1 onto 10-nt and 5-nt gapped DNAs. At a 10-nt gap we captured five Rad24-RFC-9-1-1 loading intermediates in which the 9-1-1 DNA entry gate varies from fully open to fully closed around DNA using ATPγS, supporting the emerging view that ATP hydrolysis is not needed for clamp opening/closing, but instead for dissociation of the loader from the clamp encircling DNA. The structure of Rad24-RFC-9-1-1 at a 5-nt gap shows a 180° axially rotated 3'-dsDNA which orients the template strand to bridge the 3'- and 5'- junctions with a minimum 5-nt ssDNA. The structures reveal a unique loop on Rad24 that limits the length of dsDNA in the inner chamber, and inability to melt DNA ends unlike RFC, thereby explaining Rad24-RFC's preference for a preexisting ssDNA gap and suggesting a direct role in gap repair in addition to its checkpoint role.

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.
