Description
DDX3 is a DEAD-box group protein and multifunctional ATP-dependent RNA helicase. It is involved in several cellular activities, including innate immunity, viral reproduction, and tumorigenesis. DDX3 unwinds various forms of dsRNA, both 5' - 3' and 3' - 5'. It requires ATP and Mg²+ to unwind and releases RNA via ATP hydrolysis. DDX3 is involved in transcription regulation, in innate immunity acting as a viral RNA sensor and binds viral RNAs promoting the production of type I interferon (IFN-alpha and IFN-beta). In some viruses, such as HIV, DDX3 enables viral replication, while in others (such as Dengue), it has an anti-viral effect. The RNA helicase has similar effects in some cancer studies, wherein one type of DDX3 is a tumor suppressor, while in another it acts as an enhancer. These qualities make DDX3 an interesting target for treating a variety of diseases. DDX3X has been attributed a role in NLRP3 inflammasome activation. DDX3X binds the central NACHT domain of NLRP3 to facilitate NLRP3 oligomerization and inflammasome assembly, both of which are key to NLRP3 inflammasome activation.
