Summary: Enables 3'-5' DNA helicase activity and single-stranded DNA binding activity. Involved in several processes, including DNA geometric change; DNA metabolic process; and positive regulation of G2/M transition of mitotic cell cycle. Located in cytoplasm and nucleus. Colocalizes with chromatin. Is expressed in several structures, including embryonic/larval optic lobe; embryonic/larval salivary gland; gonad; imaginal disc; and mitotic domain. Human ortholog(s) of this gene implicated in Baller-Gerold syndrome; Rothmund-Thomson syndrome; and rapadilino syndrome. Orthologous to human RECQL4 (RecQ like helicase 4).
