The protein encoded by this gene has a nuclear and a cytoplasmic form and is a member of both the dynamin family and the family of large GTPases. The nuclear form is localized in a granular pattern in the heterochromatin region beneath the nuclear envelope. A nuclear localization signal (NLS) is present at the amino terminal end of the nuclear form but is lacking in the cytoplasmic form due to use of an alternate translation start codon. This protein is upregulated by interferon-alpha but does not contain the antiviral activity of a similar myxovirus resistance protein 1. [provided by RefSeq, Jul 2008]

A study in human traumatic brain injury (TBI) patients identified the MX2 as a long noncoding RNA that forms a coexpressed pair with CXCR1, exhibiting a positive correlation of 0.9998 and association with cytokine-cytokine receptor interaction, chemokine signaling, and endocytosis pathways [Zhang et al. DOI:10.097/WNR.0000000000001756].
