Domain architecture of Rad24-RFC, 9-1-1 clamp, and the 10-nt gapped DNA. The Rfc2-5 and three subunits of 9-1-1 have similar respective domain arrangements and are shown together for brevity. Dashed lines indicate unsolved regions in EM maps. LL is the long linker between the Rad24 AAA+ module and the collar domain. The N-terminal domain (NTD) and CTD in each 9-1-1 subunit are linked by the inter-domain connecting loop (IDCL). The 10-nt gapped DNA harbors both 5' and 3' junctions.
