This gene encodes a guanosine triphosphate (GTP)-metabolizing protein that participates in the cellular antiviral response. The encoded protein is induced by type I and type II interferons and antagonizes the replication process of several different RNA and DNA viruses. There is a related gene located adjacent to this gene on chromosome 21, and there are multiple pseudogenes located in a cluster on chromosome 4. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]
A study in humans identified the MX1 as a high-degree node in a protein-protein interaction network and a potential myocardial infarction biomarker, showing significant upregulation in patient blood samples which was validated in an independent dataset [Zhao et al. DOI:10.3892/etm.2017.5580]. In a mouse model of traumatic brain injury, the MX1 was significantly upregulated in isolated microglia at 14 days post-injury, identified as part of the IFNγ pathway [Izzy et al. DOI:10.3389/fncel.2019.00307]. A separate bioinformatics analysis in humans identified the MX1 as a key hub protein and a cardiac disease predictive biomarker in cardiomyopathy, with receiver operating characteristic curve analysis demonstrating an area under the curve of 0.716 for its diagnostic performance [Rahman et al. DOI:10.1038/s41598-024-78011-3].
