DESCRIPTION

Also known as RECQ5_HUMAN, RECQL5, RECQ5. Isoform beta is a DNA helicase that plays an important role in DNA replication, transcription and repair. Inhibits elongation of stalled transcripts at DNA damage sites by binding to the RNA polymerase II subunit POLR2A and blocking the TCEA1 binding site. Required for mitotic chromosome separation after cross-over events and cell cycle progress. Required for efficient DNA repair, including repair of inter-strand cross-links. Stimulates DNA decatenation mediated by TOP2A. Prevents sister chromatid exchange and homologous recombination. Monomer. Interacts with TOP2A, TOP3A and TOP3B. Isoform beta interacts with RNA polymerase II subunit POLR2A. Identified in a complex with the RNA polymerase II core bound to DNA. Isoform beta interacts with RAD51.
