Ubiquitin (Ub)-mediated xenophagy is important in defense against Mycobacterium tuberculosis (Mtb). Here, Chai et al. describe autophagy triggering by Ub binding to the Mtb surface protein Rv1468c, and show that its deletion leads to increased bacterial loads and hyperinflammatory responses in mice.
