General annotation (Comments)
| Function | Component of the LUBAC complex which conjugates linear polyubiquitin chains in a head-to-tail manner 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. Ref.10 Ref.11 Ref.12 |
| Subunit structure | Monomer and homodimer. Interacts with SHANK1, EYA1 and EYA2 By similarity. Component of the LUBAC complex (linear ubiquitin chain assembly complex) which consists of SHARPIN, RBCK1 and RNF31. LUBAC has a MW of approximative 600 kDa suggesting a heteromultimeric assembly of its subunits. Associates with the TNF-R1 signaling complex (TNF-RSC) in a stimulation-dependent manner. Ref.10 Ref.11 Ref.12 Ref.13 |
| Subcellular location | |
| Tissue specificity | Highly expressed in skeletal muscle and placenta and at lower levels in brain, heart, colon without mucosa, thymus, spleen, kidney, liver, small intestine, lung and peripheral blood leukocytes. Up-regulated in various tumor tissues such as kidney, liver, ovary and pancreas tumors. Ref.2 |
| Domain | The Ubiquitin-like domain is required for the interaction with RNF31. Ref.10 Ref.11 Ref.12 The RanBP2-type zinc fingers mediate the specific interaction with ubiquitin. Binds preferentially linear polyubiquitin chains and 'Lys-63'-linked polyubiquitin chains over 'Lys-48'-linked polyubiquitin chains. Also binds monoubiquitin. Ref.10 Ref.11 Ref.12 |
| Sequence similarities | Contains 1 RanBP2-type zinc finger. Contains 1 ubiquitin-like domain. |
| Sequence caution | The sequence BAC11666.1 differs from that shown. Reason: Frameshift at position 334. The sequence BAC53797.1 differs from that shown. Reason: Frameshift at position 218. The sequence BAC53798.1 differs from that shown. Reason: Aberrant splicing. |
