    Cooperative interactions facilitate stimulation of Rad51 by the Swi5-Sfr1 auxiliary factor complex

    Bilge Argunhan et al.
    The intrinsically disordered N-terminus of Sfr1 contains two Rad51 binding sites that facilitate Rad51 filament stabilization and ATPase stimulation by the Swi5-Sfr1 complex, leading to efficient Rad51-driven strand exchange.

    A novel motif of Rad51 serves as an interaction hub for recombination auxiliary factors

    Negar Afshar et al.
    Although Rad51 is the central protein involved in recombinational DNA repair, multiple auxiliary factors potentiate its activity by binding to a single, evolutionarily conserved motif.

    Rad52-Rad51 association is essential to protect Rad51 filaments against Srs2, but facultative for filament formation

    Emilie Ma et al.
    The association of Rad52 with Rad51, while not critical for Rad51 filament formation, is crucial to protect Rad51 filaments from Srs2 translocase activity through the association of Rad52 with complete Rad51 filaments.

    Rdh54/Tid1 inhibits Rad51-Rad54-mediated D-loop formation and limits D-loop length

    Shanaya Shital Shah et al.
    The dsDNA-dependent motor protein Rdh54 antagonizes Rad51-Rad54-mediated D-loop formation during homologous recombination and restricts the length of D-loops.

    Harmful DNA:RNA hybrids are formed in cis and in a Rad51-independent manner

    Juan Lafuente-Barquero et al.
    RNA does not form DNA:RNA hybrids in trans that compromise genome integrity.

    Spatial control of translation repression and polarized growth by conserved NDR kinase Orb6 and RNA-binding protein Sts5

    Illyce Nuñez et al.
    NDR kinase Orb6 prevents RNP granule assembly and translational repression by promoting Sts5 association with 14-3-3 protein Rad24 to spatially control polarized cell growth.

    Distinct roles of ATM and ATR in the regulation of ARP8 phosphorylation to prevent chromosome translocations

    Jiying Sun et al.
    ATM plays an important role in maintaining the fidelity of DNA repair through the regulation of ARP8 phosphorylation to prevent the chromosome abnormality.

    Determining cellular CTCF and cohesin abundances to constrain 3D genome models

    Claudia Cattoglio et al.
    Absolute quantification of CTCF and cohesin reveals quantitative constraints on 3D genome organization and illuminates the molecular architecture of the cohesin complex.

    A missense in HSF2BP causing primary ovarian insufficiency affects meiotic recombination by its novel interactor C19ORF57/BRME1

    Natalia Felipe-Medina et al.
    Genetic and biochemical analysis reveal a variant in HSF2BP causing POI and C19ORF57/BRME1 as an interactor and stabilizer of HSF2BP by forming a complex with BRCA2, RAD51, RPA and PALB2.

    Novel RNA and DNA strand exchange activity of the PALB2 DNA binding domain and its critical role for DNA repair in cells

    Jaigeeth Deveryshetty et al.
    Biochemical studies revealed novel property of human tumor suppressor PALB2, which significantly contribute into DNA repair in cells and can be targeted for the development of novel anticancer treatment.
