High impact information on FBXO18

  • However, FBH1(-)(/)(-) cells exhibit increases in both sister chromatid exchange and the formation of radial structures between homologous chromosomes without showing a defect in homologous recombination [1].
  • This phenotype is reminiscent of BLM(-)(/)(-) cells and suggests that Fbh1 may be involved in preventing extensive strand exchange during homologous recombination [1].
  • In addition, disruption of RAD54, a major homologous recombination factor in FBH1(-)(/)(-) cells, results in a marked increase in chromosome-type breaks (breaks on both sister chromatids at the same place) following replication fork arrest [1].
  • Recombinant hFBH1, containing glutathione S-transferase at the N terminus, was expressed in Sf9 cells and purified [2].
