Properties of different human and murine Mx proteins

Protein	Cellular localization	Illustrative antiviral activitya	References
Human MxA	Cytoplasmic condensates with some tethered to intermediate filaments	Versus both FLUAV and VSV	9, 29,30, 31, 32, 33, 34,35
Human MxB (full-length)	Cytoplasmic face of nuclear pores	Versus HIV; not versus FLUAV nor VSV	31, 39,40, 41, 42, 43,44
	Cytoplasmic condensates		Our inference
Murine Mx1	Nuclear condensates	Versus FLUAV; not VSV	This study and Refs. 29–31, 35, 36
	Cytoplasmic intermediate filaments and condensates	Versus VSV	This study
Murine Mx2	Cytoplasmic structures	Versus VSV; not FLUAV	31, 35–37
