  • 功能：
    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.
  • 基因功能参考文献：
    1. It has been shown that conjugation of SUMO2, but not SUMO1 or SUMO3, to the essential replication factor PCNA is induced on transcribed chromatin by the RNAPII-bound helicase RECQ5. PMID: 30006506
    2. we have shown that increased expression of RECQL5 protein occurs and is likely to contribute to tumourigenesis in UCC and that the pharmacological targeting of the helicase activity of RECQL5 is a strong target for future small molecule inhibitor development. PMID: 27764811
    3. RECQ5 removes RAD51 filaments stabilizing stalled replication forks at common fragile sites and hence facilitates CFS cleavage by MUS81-EME1. PMID: 28575661
    4. the open and closed forms of RECQL5 were used together with a quantitative comparison of all current RecQ family structures to construct a mechanistic model for RECQL5 helicase activity PMID: 28100692

    6. interaction between RECQ5 and proliferating cell nuclear antigen (PCNA) promotes RAD18-dependent PCNA ubiquitination and the helicase activity of RECQ5 promotes the processing of replication intermediates. PMID: 27502483
    7. RECQL5 has unique strand annealing properties relative to the other human RecQ helicase proteins PMID: 26717024
    8. RECQL5 is a critical regulator of genome stability in myeloproliferative neoplasms and demonstrate that replication stress-associated cytotoxicity can be amplified specifically in JAK2V617F mutant cells through RECQL5-targeted synthetic lethality. PMID: 26686625

    16. The data presented here provide evidence that RECQL5 plays a general role in the control of transcript elongation in human cells.

    21. RECQL5 contacts the Rpb1 jaw domain of Pol II at a site that overlaps with the binding site for the transcription elongation factor TFIIS. Binding of RECQL5 to Pol II interferes with the ability of TFIIS to promote transcriptional read-through in vitro. PMID: 23748380
