Gene Group (FlyBase)
RAD51-LIKE ATPASES -
Rad51-like ATPases include RAD51 and its paralogs, which play an essential role in repair of double-strand DNA breaks through homologous recombination. They act to transduce the DNA damage signal to effector kinases and to promote break repair. (Adapted from PMID:21821141.)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)

            New annotation (CG31069) in release 3 of the genome annotation.

            Analysis of mutants of the 5 spindle genes (spn-A, spn-B, mus301, spn-D and spn-E) reveals that the group of genes is required for each of the symmetry-breaking steps that generate polarity during axis formation. spn-E is required for the localisation of fs(1)K10, bcd and osk mRNAs, spn-A. spn-B, mus301 and spn-D play an indirect role in this process. Double mutants analysis suggests that spn-B and spn-D genes play a partially redundant role in oocyte positioning.

            Mutations in the spn-A, spn-B and spn-D genes result in a very similar phenotype to those in mus301, and in all cases the misplacement of the oocyte has the same consequences on the establishment of AP polarity in the egg chamber, as determined by the slbo expression in the follicle cells and the localization of osk and bcd mRNAs within the oocyte.
