RECQL5
Description
The RECQL5 (RecQ like helicase 5) is a protein-coding gene located on chromosome 17.
ATP-dependent DNA helicase Q5 is an enzyme that in humans is encoded by the RECQL5 gene.
DNA helicase that plays an important role in DNA replication, transcription and repair (PubMed:20643585, PubMed:22973052, PubMed:28100692). Probably unwinds DNA in a 3'-5' direction (PubMed:28100692) (Probable). Binds to the RNA polymerase II subunit POLR2A during transcription elongation and suppresses transcription- associated genomic instability (PubMed:20231364). Associates also with POLR1A and enforces the stability of ribosomal DNA arrays (PubMed:27502483). Plays an important role in mitotic chromosome separation after cross-over events and cell cycle progress (PubMed:22013166). Mechanistically, removes RAD51 filaments protecting stalled replication forks at common fragile sites and stimulates MUS81- EME1 endonuclease leading to mitotic DNA synthesis (PubMed:28575661). Required for efficient DNA repair, including repair of inter-strand cross-links (PubMed:23715498). Stimulates DNA decatenation mediated by TOP2A. Prevents sister chromatid exchange and homologous recombination. A core helicase fragment (residues 11-609) binds preferentially to splayed duplex, looped and ssDNA (PubMed:28100692). {ECO:0000269|PubMed:20231364, ECO:0000269|PubMed:20348101, ECO:0000269|PubMed:20643585, ECO:0000269|PubMed:22013166, ECO:0000269|PubMed:22973052, ECO:0000269|PubMed:23715498, ECO:0000269|PubMed:23748380, ECO:0000269|PubMed:27502483, ECO:0000269|PubMed:28100692, ECO:0000269|PubMed:28575661, ECO:0000305|PubMed:28100692}
