CC -!- FUNCTION: Component of the LUBAC complex which conjugates linear
CC polyubiquitin chains in a head-to-tail manner to substrates and plays a
CC key role in NF-kappa-B activation and regulation of inflammation. LUBAC
CC conjugates linear polyubiquitin to IKBKG and RIPK1 and is involved in
CC activation of the canonical NF-kappa-B and the JNK signaling pathways.
CC Linear ubiquitination mediated by the LUBAC complex interferes with
CC TNF-induced cell death and thereby prevents inflammation. LUBAC is
CC recruited to the TNF-R1 signaling complex (TNF-RSC) following
CC polyubiquitination of TNF-RSC components by BIRC2 and/or BIRC3 and to
CC conjugate linear polyubiquitin to IKBKG and possibly other components
CC contributing to the stability of the complex. The LUBAC complex is also
CC involved in innate immunity by conjugating linear polyubiquitin chains
CC at the surface of bacteria invading the cytosol to form the ubiquitin
CC coat surrounding bacteria. LUBAC is not able to initiate formation of
CC the bacterial ubiquitin coat, and can only promote formation of linear
CC polyubiquitins on pre-existing ubiquitin. The bacterial ubiquitin coat
CC acts as an 'eat-me' signal for xenophagy and promotes NF-kappa-B
CC activation. Together with OTULIN, the LUBAC complex regulates the
CC canonical Wnt signaling during angiogenesis.
CC {ECO:0000250|UniProtKB:Q9H0F6}.
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC {ECO:0000250|UniProtKB:Q9H0F6}.
CC -!- SUBUNIT: Monomer and homodimer (PubMed:11178875). Component of the
CC LUBAC complex (linear ubiquitin chain assembly complex) which consists
CC of SHARPIN, RBCK1 and RNF31 (By similarity). LUBAC has a MW of
CC approximately 600 kDa suggesting a heteromultimeric assembly of its
CC subunits (By similarity). Associates with the TNF-R1 signaling complex
CC (TNF-RSC) in a stimulation-dependent manner (By similarity). Interacts
CC with EYA1, EYA2, SHANK1 and SHANK3 (via ANK repeats) (PubMed:11178875,
CC PubMed:23897824). {ECO:0000250|UniProtKB:Q9H0F6,
CC ECO:0000269|PubMed:11178875, ECO:0000269|PubMed:23897824}.

CC Q9EQL9; Q9EQL9: Sharpin; NbExp=2; IntAct=EBI-1394695, EBI-1394695;
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:11178875}. Synapse
CC {ECO:0000269|PubMed:11178875}. Note=Enriched at synaptic sites in
CC mature neurons where it colocalizes with SHANK1.
CC {ECO:0000269|PubMed:11178875}.
CC -!- TISSUE SPECIFICITY: Expressed in brain, spleen, lung, heart, skeletal
CC muscle, kidney and testis (at protein level). Expressed in heart and
CC testis. {ECO:0000269|PubMed:11178875}.
CC -!- DOMAIN: The Ubiquitin-like domain is required for the interaction with
CC RNF31. {ECO:0000250}.
CC -!- DOMAIN: The RanBP2-type zinc fingers mediate the specific interaction
CC with ubiquitin. Binds preferentially linear polyubiquitin chains and
CC 'Lys-63'-linked polyubiquitin chains over 'Lys-48'-linked polyubiquitin
CC chains. Also binds monoubiquitin (By similarity). {ECO:0000250}.
