Function |
Participates in DNA replication and repair. Exhibits a magnesium-dependent ATP-dependent DNA-helicase activity that unwinds single- and double-stranded DNA in a 3'-5' direction. Involved in 5'-end resection of DNA during double-strand break (DSB) repair: unwinds DNA and recruits DNA2 which mediates the cleavage of 5'-ssDNA. Negatively regulates sister chromatid exchange (SCE). {ECO:0000269|PubMed:9840919}.
|
Subcellular Location |
Nucleus {ECO:0000250}. Note=Together with SPIDR, is redistributed in discrete nuclear DNA damage-induced foci following hydroxyurea (HU) or camptothecin (CPT) treatment. Accumulated at sites of DNA damage in a RMI complex- and SPIDR- dependent manner (By similarity). {ECO:0000250}.
|
Tissue Specificity |
Highly expressed in testis 12-14 days after birth (corresponding to the pachytene phase) and at much lower levels in brain, heart, liver, lung, thymus, kidney and spleen. {ECO:0000269|PubMed:9655940}.
