Summaries
UniProt Contributed Function Data
Involved in mitotic DNA repair and meiotic recombination. Functions in the recombinational DNA repair pathway. Essential for interhomolog gene conversion (GC), but may have a less important role in intersister GC than spn-A/Rad51. In the presence of DNA, spn-A/Rad51 enhances the ATPase activity of okr/Rad54.
(UniProt, O76460)
Phenotypic Description from the Red Book (Lindsley and Zimm 1992)
okr: okra (T. Schupbach)
Female sterile; homozygous females lay eggs which are of variable shapes; in the most extreme cases, the eggs are longer than normal, more pointed at the posterior end, and lack dorsal appendages, resembling eggs produced by the dominant female-sterile mutation Fs(2)D.

      Gene is involved in post-replication recombination repair.
      Characterisation of mutants implies okr is crucial in repair and recombination.
      Mutant phenotype is consistent with a defect in the repair of double-stranded breaks.
      Mutations at the okr locus cause defects in midoogenesis.
