Evidence Summary from Illumina curation team: MX2, also known as MXB is an interferon-induced dynamin like GTPAse with antiviral activity, which has been shown to affect the nuclear uptake and/or stability of the HIV-1 replication complex and the subsequent chromosomal integration of the proviral DNA (Goujon et al. 2013, Liu et al. 2015). However, resistance of several HIV strains to MX2-driven inhibition has been reported (Liu et al. 2015). Inhibition of other viruses, including HCV, Japanese encephalitis virus and Dengue virus of the Flaviviridae family as well as simian immunodeficiency virus and Herpesviruses has been reported (Goujon et al. 2013, Yi et al. 2019). In contrast to MX1, MX2 does not appear to be involved in regulation of several other viral infections, including influenza and Zika virus (Melen et al. 1996; Yi et al. 2019). Additionally, MX2 may be involved in nucleocytoplasmic transport and bears a nuclear localisation signal that appears essential for HCV inhibition (Melen et al. 1996; King et al. 2004, Yi et al. 2019). Of note, MX2 was described as an interferon response marker gene in preprint studies investigating expression profiles and related mechanisms in SARS-CoV-2 infection (Fagone et al. 2020, Li et al. 2020). Overall, inhibition of viral infection by MX2 appears to be virus type- and strain-specific, and some viruses potentially have developed mechanisms to resist MX2 function. No reports of any SNP associations of MX2 with viral susceptibility in humans have been identified.
