Our Abpromise guarantee covers the use of ab45428 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
ICC/IF Use a concentration of 5 µg/ml.

靶标

  • 功能Involved in innate immune defense against viruses. Upon interaction with intracellular dsRNA produced during viral replication, triggers a transduction cascade involving MAVS/IPS1, which results in the activation of NF-kappa-B, IRF3 and IRF7 and the induction of the expression of antiviral cytokines such as IFN-beta and RANTES (CCL5). Detects dsRNA produced from non-self dsDNA by RNA polymerase III, such as Epstein-Barr virus-encoded RNAs (EBERs). Essential for the production of interferons in response to RNA viruses including paramyxoviruses, influenza viruses, Japanese encephalitis virus and HCV.
  • 组织特异性Present in vascular smooth cells (at protein level).
  • 序列相似性Belongs to the helicase family.
    Contains 2 CARD domains.
    Contains 1 helicase ATP-binding domain.
    Contains 1 helicase C-terminal domain.
  • 结构域The repressor domain controls homomultimerization and interaction with MAVS.
    The helicase domain is responsible for dsRNA recognition.
    The 2 CARD domains are responsible for interaction with and signaling through MAVS.
    The second CARD domain is the primary site for 'Lys-63'-linked ubiquitination.
  • 翻译后修饰Isgylated. Conjugated to ubiquitin-like protein ISG15 upon IFN-beta stimulation.
    Ubiquitinated. Undergoes 'Lys-63'-linked ubiquitination. Lys-172 is the critical site for TRIM25-mediated ubiquitination, for MAVS binding and to induce anti-viral signal transduction. Lys-154, Lys-164 and Lys-172 are critical sites for RNF135-mediated ubiquitination. Deubiquitinated by CYLD, a protease that selectively cleaves 'Lys-63'-linked ubiquitin chains.
  • 细胞定位Cytoplasm. Colocalized with TRIM25 at cytoplasmic perinuclear bodies.

    Observed band size : 85 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 65 kDa,70 kDa. We are unsure as to the identity of these extra bands.
  • ab45428 at 5 µg/ml staining DDX58 in human heart tissue section by Immunohistochemistry (Formalin/ PFA fixed paraffin-embedded tissue sections).

  • ICC/IF image of ab45428 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab45428, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
