[[http://www.uniprot.org/uniprot/RNF31_HUMAN RNF31_HUMAN]] E3 ubiquitin-protein ligase component of the LUBAC complex which conjugates linear ('M-1'-linked) polyubiquitin chains to substrates and plays a key role in NF-kappa-B activation and regulation of inflammation. LUBAC conjugates linear polyubiquitin to IKBKG and RIPK1 and is involved in activation of the canonical NF-kappa-B and the JNK signaling pathways. Linear ubiquitination mediated by the LUBAC complex interferes with TNF-induced cell death and thereby prevents inflammation. LUBAC is proposed to be recruited to the TNF-R1 signaling complex (TNF-RSC) following polyubiquitination of TNF-RSC components by BIRC2 and/or BIRC3 and to conjugate linear polyubiquitin to IKBKG and possibly other components contributing to the stability of the complex. Binds polyubiquitin of different linkage types.<ref>PMID:17006537</ref> <ref>PMID:20005846</ref> <ref>PMID:19136968</ref> <ref>PMID:21455173</ref> <ref>PMID:21455180</ref> <ref>PMID:21455181</ref> <ref>PMID:22863777</ref>
