Product Overview
This rabbit polyclonal antibody detects ATP-dependent RNA helicase DDX3X in human, monkey, mouse and rat samples and is validated for Western blot, ICC/IF and flow cytometry. The predicted molecular weight is 73.2 kDa, and the supplier reports an observed band at about 73 kDa.
DDX3X is a multifunctional DEAD-box RNA helicase that helps unwind structured 5′-UTRs to promote translation initiation. It also contributes to mRNA export, stress granule formation and innate immune signaling that leads to type I interferon production. DDX3X is studied in translation control, antiviral immunity, neurodevelopment and cancer.

Immunogen
Synthetic peptide from the N-terminal region of human DDX3/DDX3X. The peptide sequence is conserved in mouse.
Reactivity Notes
The supplier lists reactivity with human, monkey, mouse and rat. UniProt places ATP-dependent RNA helicase DDX3X in the cell membrane, nucleus, cytoplasm and inflammasome. Tissue expression noted by UniProt (human): Widely expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
