PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	a nuclear localization signal (NLS) is present at the N-terminal end of the nuclear form but is lacking in the cytoplasmic form, basic nuclear localization signal (NLS) contained within its N-terminal 25 amino acids, and strictly required for antiviral activity
	a GED domain

HOMOLOGY

interspecies	homolog to murine Mx2 and Mx1
	homolog to C.elegans T12E12.4

intraspecies

homolog to MX2

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic
	intracellular,nucleus,chromatin/chromosome,heterochromosome
text	having a nuclear and a cytoplasmic form
	the nuclear form is localized in a granular pattern in the heterochromatin region beneath the nuclear envelope
	only MX2 is localized to the nucleus (not MX1) (PmID: 24121441)

basic FUNCTION	is a narcolepsy-specific dysregulated gene, and there exists a relationship between the HLA-DQB1*0602 allele and MX2 gene expression
	MX1 and MX2 are intracellular proteins that are induced exclusively by type I IFNs
	potent inhibitor of HIV-1 infection and as a key effector of IFNA2-mediated resistance to HIV-1 infection, but is ineffective against influenza virus
	MX2 inhibits the nuclear accumulation and integration of HIV-1 reverse transcripts
	inhibits HIV-1 infection by inhibiting capsid-dependent nuclear import of subviral complexes
	is an effector in the anti-HIV-1 activity of type I IFN
