Immunity-related GTPase family M protein (IRGM) is a ~20 kDa protein. Immunity-related GTPase that plays important roles in innate immunity and inflammatory response. Acts as a dynamin-like protein that binds to intracellular membranes and promotes remodeling and trafficking of those membranes. Required for clearance of acute protozoan and bacterial infections by interacting with autophagy and lysosome regulatory proteins, thereby promoting the fusion of phagosomes with lysosomes for efficient degradation of cargo including microbes. Regulates selective autophagy, including xenophagy and mitophagy, both directly and indirectly. Directly regulates autophagy by acting as a molecular adapter that promotes the coassembly of the core autophagy machinery to mediate antimicrobial defense: IRGM (1) activates AMPK, which in turn phosphorylates ULK1 and BECN1 to induce autophagy, (2) promotes the coassembly of ULK1 and BECN1, enhancing BECN1-interacting partners and (3) influences the composition of the BECN1 complex, by competing with the negative regulators BCL2 and RUBCN, to trigger autophagy.
