DESCRIPTION
Also known as DHX9_XENLA, dhx9. Multifunctional ATP-dependent nucleic acid helicase that unwinds DNA and RNA in a 3' to 5' direction and that plays important roles in many processes, such as DNA replication, transcriptional activation, post-transcriptional RNA regulation, mRNA translation and RNA-mediated gene silencing. Requires a 3'-single-stranded tail as entry site for acid nuclei unwinding activities as well as the binding and hydrolyzing of any of the four ribo- or deoxyribo-nucleotide triphosphates (NTPs). Binds to DNA, RNA and small interfering siRNA. Plays a role in DNA replication at origins of replication and cell cycle progression. Plays a role as a transcriptional coactivator acting as a bridging factor between polymerase II holoenzyme and transcription factors or cofactors. Plays several roles in post-transcriptional regulation of gene expression. Promotes pre-mRNA alternative splicing activities of a subset of genes. As component of a large PER complex, is involved in the negative regulation of 3' transcriptional termination of circadian target genes. Component of the coding region determinant (CRD)-mediated complex that promotes cytoplasmic MYC mRNA stability. Plays a role in mRNA translation. Plays also a role in the RNA-induced silencing complex (RISC) loading complex (RLC) assembly, and hence functions in the RISC-mediated gene silencing process. Mediates the attachment of heterogeneous nuclear ribonucleoproteins (hnRNPs) to actin filaments in the nucleus. Component of the coding region determinant (CRD)-mediated complex. Identified in mRNP granule complexes containing untranslated mRNAs. Associates with the RISC complex. Associates with the SMN complex. Associates with polysomes.
