MxB/Mx2 is an interferon-induced dynamin-like GTPase, which restricts a number of life-threatening viruses. Because of its N-terminal region, predicted to be intrinsically disordered, and its propensity to self-oligomerize, purification of the full-length protein has not been successful in conventional E. coli expression systems. In this chapter, we describe an expression and purification procedure to obtain pure full-length wild-type MxB from suspension-adapted mammalian cells. We further describe how to characterize its GTPase activity and oligomerization function.
