Protein Structure
UniProt Annotation
Function Unwinds duplex DNA with 5'-3' polarity. Has single- strand DNA-dependent ATPase and DNA helicase activities. Prefers ATP and dATP as substrates. During S phase, may facilitate cellular recovery from replication stress. {ECO:0000269PubMed:12181327, ECO:0000269PubMed:22194613}.
Subcellular Localization Note=Preferentially during S phase, recruited to chromatin following DNA damage induced by UV irradiation, or camptothecin or hydroxyurea treatment.
Disease Associations
Tissue Specificity Highly expressed in testis and thymus and weakly in liver, spleen, kidney and brain. {ECO:0000269PubMed:12181327}.
