==Overview==

==Recombination mediator RecF==
-
RecF, together with RecO and RecR, belongs to a ubiquitous group of, recombination mediators (RMs) that includes eukaryotic proteins such as, Rad52 and BRCA2. RMs help maintain genome stability in the presence of DNA, damage by loading RecA-like recombinases and displacing single-stranded, DNA-binding proteins. Here, we present the crystal structure of RecF from, Deinococcus radiodurans. RecF exhibits a high degree of structural, similarity with the head domain of Rad50, but lacks its long coiled-coil, region. The structural homology between RecF and Rad50 is extensive, encompassing the ATPase subdomain and the so-called 'Lobe II' subdomain of, Rad50. The pronounced structural conservation between bacterial RecF and, evolutionarily diverged eukaryotic Rad50 implies a conserved mechanism of, DNA binding and recognition of the boundaries of double-stranded DNA, regions. The RecF structure, mutagenesis of conserved motifs and, ATP-dependent dimerization of RecF are discussed with respect to its role, in promoting presynaptic complex formation at DNA damage sites.

[https://www.uniprot.org/uniprot/RECF_DEIRA RECF_DEIRA] The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. RecF binds preferentially to single-stranded, linear DNA. It also seems to bind ATP (By similarity).

RecF, together with RecO and RecR, belongs to a ubiquitous group of recombination mediators (RMs) that includes eukaryotic proteins such as Rad52 and BRCA2.

Here, we present the crystal structure of RecF from Deinococcus radiodurans. RecF exhibits a high degree of structural similarity with the head domain of Rad50, but lacks its long coiled-coil region. The structural homology between RecF and Rad50 is extensive, encompassing the ATPase subdomain and the so-called 'Lobe II' subdomain of Rad50. The pronounced structural conservation between bacterial RecF and evolutionarily diverged eukaryotic Rad50 implies a conserved mechanism of DNA binding and recognition of the boundaries of double-stranded DNA regions. The RecF structure, mutagenesis of conserved motifs and ATP-dependent dimerization of RecF are discussed with respect to its role in promoting presynaptic complex formation at DNA damage sites.
