The MxA inflammasome. Myxovirus resistance protein A (MxA) contains a dynamin-type GTPase domain, a middle domain, and a GTPase effector domain that forms a stalk-like structure. During influenza A virus infection, the GTPase domain of MxA binds to the pyrin domain of an apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), promoting inflammasome activation
