    What's a GeneRIF?
    1. Study provides evidence that DNA-binding components of the budding yeast Shu complex, Csm2-Psy3, bind double-flap DNA substrates containing an abasic site analog, and increase chromatin association when abasic sites accumulate. Importantly, Csm2-Psy3 blocks AP endonuclease cleavage at a double-flap DNA substrate, thus preventing in vitro double-strand break formation.
      Title: The Rad51 paralogs facilitate a novel DNA strand specific damage tolerance pathway.
    2. Data indicate that Csm2, Psy3, Shu1 and Shu2 interact with each other in sequence to form a V-shape overall structure in Shu complex.
      Title: Structural basis for the functional role of the Shu complex in homologous recombination.
    3. The data suggest a model in which Csm2-Psy3 recruit the Shu complex to homologous recombination substrates, where it interacts with Rad51 through Rad55-Rad57 to stimulate Rad51 filament assembly and stability, promoting error-free repair.

    • Component of Shu complex (aka PCSS complex); Shu complex also includes Shu1, Csm2, Shu2, and promotes error-free DNA repair; promotes Rad51p filament assembly; Shu complex mediates inhibition of Srs2p function; Psy3p and Csm2p contain similar DNA-binding regions which work together to form a single DNA binding site; deletion of PSY3 results in a mutator phenotype; deletion increases sensitivity to anticancer drugs oxaliplatin and cisplatin but not mitomycin C
