  • 产品描述：

    DDX5 is an ATP-dependent RNA helicase involved in splicing, mRNA export, transcript stability, rRNA biosynthesis, and microRNA processing, among other RNA-related events. DDX5 has been connected to the regulation of numerous cancer-related pathways and has been found to be abnormally expressed in many cancers. DDX5 is closely linked to carcinogenesis, invasiveness, and metastasis, as well as cancer proliferation in several cancers. Dysfunction of DDX5 is ultimately associated with tumor formation and progression.

    CUSABIO designed the vector clones for the expression of a recombinant DDX5 antibody in mammalian cells. The vector clones were obtained by inserting the DDX5 antibody heavy and light chains into the plasma vectors. The recombinant DDX5 antibody was purified from the culture medium through Affinity-chromatography. It can be used to detect DDX5 protein from Human, Mouse in the ELISA, WB, IHC, IF, FC.

  • 功能：
    Involved in the alternative regulation of pre-mRNA splicing; its RNA helicase activity is necessary for increasing tau exon 10 inclusion and occurs in a RBM4-dependent manner. Binds to the tau pre-mRNA in the stem-loop region downstream of exon 10. The rate of ATP hydrolysis is highly stimulated by single-stranded RNA. Involved in transcriptional regulation; the function is independent of the RNA helicase activity. Transcriptional coactivator for androgen receptor AR but probably not ESR1. Synergizes with DDX17 and SRA1 RNA to activate MYOD1 transcriptional activity and involved in skeletal muscle differentiation. Transcriptional coactivator for p53/TP53 and involved in p53/TP53 transcriptional response to DNA damage and p53/TP53-dependent apoptosis. Transcriptional coactivator for RUNX2 and involved in regulation of osteoblast differentiation. Acts as transcriptional repressor in a promoter-specific manner; the function probably involves association with histone deacetylases, such as HDAC1. As component of a large PER complex is involved in the inhibition of 3' transcriptional termination of circadian target genes such as PER1 and NR1D1 and the control of the circadian rhythms.
