MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a DNA-dependent ATPase which catalyzes the unwinding of DNA necessary for DNA replication, repair, recombination, and transcription. This gene is thought to function specifically during the S phase entry of the cell cycle. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]
PHENOTYPE: Homozygous knockout MEFs display increased DNA end resection, resulting in increased level of single-strand DNA formation at double-strand DNA breaks. [provided by MGI curators]
