DDX3X and viral infectious disease: Other IRES that display DDX3X regulation include those present in HCV (Geissler et al., 2012; Pène et al., 2015; Su et al., 2018), encephalomyocarditis virus (EMCV), Echovirus 9, and Coxsackievirus 16, clearly illustrating the extensive contribution of DDX3X-mediated non-canonical translation to viral infections (Su et al., 2018).
