UniProtKB description: E3 ubiquitin-protein ligase effector that inhibits host cell innate immunity during bacterial infection by catalyzing 'Lys-48'-linked polyubiquitination and subsequent degradation of host RNF31/HOIP (PubMed:27572974, PubMed:36610722). Host RNF31/HOIP is the catalytic component of the LUBAC complex, which conjugates linear ('Met-1'-linked) polyubiquitin chains at the surface of bacteria invading the host cytosol to form the ubiquitin coat surrounding bacteria (PubMed:27572974). The bacterial ubiquitin coat acts as an 'eat-me' signal for xenophagy and promotes NF-kappa-B activation (PubMed:27572974).
