    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala25 of human DHX9 protein. Antibodies are purified by peptide affinity chromatography.

    Background

    DExH-box helicase 9 (DHX9), also known as nuclear DNA helicase II or RNA helicase A, is a protein involved in unwinding DNA and RNA by using NTP (1). DHX9 can translocate in the 3’ to 5’ direction and can utilize all dNTPs or rNTPs, and contributes to pre-mRNA splicing (2,3). Essential for embryo development, DHX9 plays roles in many biological processes, including DNA replication, self-renewal, dosage compensation, and neuronal development (4-7). DHX9 is a critical regulator of abnormal DNA secondary structures (8). It is recruited by TDRD3 to R-loops, where it can unwind and resolve them to prevent DNA damage (9-12). DHX9 plays a central role in the formation and resolution of R-loops (8-11). It also can bind to G-quadruplexes and inverted-repeat Alu elements, suppressing formation of circular RNAs (9,13). BRCA1 is recruited to RNA by DHX9 to promote homologous recombination (14). Furthermore, DHX9 has been shown to be upregulated in various cancer types and can also play a role in viral replication (15-17).
