What's a GeneRIF?

Helicase Q promotes homology-driven DNA double-strand break repair and prevents tandem duplications.
Title: Helicase Q promotes homology-driven DNA double-strand break repair and prevents tandem duplications.
Analyses of jmjd-5 genetic interactions with genes required for resolving recombination intermediates (rtel-1) or promoting the resolution of RAD-51 double stranded DNA filaments (rfs-1 and helq-1) suggest that jmjd-5 prevents the formation of stalled postsynaptic recombination intermediates and favors RAD-51 removal.
Title: JMJD-5/KDM8 regulates H3K36me2 and is required for late steps of homologous recombination and genome integrity.
HELQ-1 and RFS-1 independently bind to and promote the disassembly of RAD-51 from double-stranded, but not single-stranded, DNA filaments via distinct mechanisms.
Title: Overlapping mechanisms promote postsynaptic RAD-51 filament disassembly during meiotic double-strand break repair.
