RNF31 also known as HOIP (HOIL-1 Interacting Protein) is a large protein with a molecular weight of around 119 kDa. It is a part of the ubiquitin-proteasome system and functions mechanically as a E3 ubiquitin ligase. RNF31 forms the catalytic component of the Linear Ubiquitin Chain Assembly Complex (LUBAC). Expression of RNF31 occurs in many tissues with notable levels in immune cells and the testes. The protein features a RING-in-between-RING (RBR) motif structure that is critical for its ligase activity.
Biological function summary

RNF31/HOIP plays an important role in immune response regulation. It functions as part of the LUBAC complex alongside SHARPIN and RBCK1 (also known as HOIL-1L) which together catalyze the linear ubiquitination of substrates. These modifications regulate NF-kB signaling which is an important pathway involved in immune and inflammatory responses. RNF31's ubiquitin ligase activity adds linear ubiquitin chains to target proteins influencing their stability and function therefore impacting the immune cell function and survival.

Pathways

RNF31/HOIP integrates into the NF-kB and the apoptosis pathways. In the NF-kB pathway it acts as a regulator of cytokine production and cell survival. RNF31 achieves this through modification of NEMO (NF-kB essential modulator) an important protein in this pathway. In apoptosis regulation linear ubiquitination by RNF31 modulates the activity of proteins such as caspases preventing inappropriate cell death during immune responses. This helps to maintain balance between survival and death signals in cells allowing for proper immune function.

RNF31/HOIP has implications in inflammatory diseases and certain cancers. Dysregulation of LUBAC components including HOIP has been linked with chronic inflammatory conditions like rheumatoid arthritis where inappropriate NF-kB activation occurs. Furthermore aberrations in RNF31 activity have associations with tumorigenesis where its altered signaling pathways can lead to uncontrolled cell proliferation. In these contexts proteins such as A20 may interact with RNF31 affecting the regulation of NF-kB signaling therefore influencing disease progression.

Target data

E3 ubiquitin-protein ligase component of the LUBAC complex which conjugates linear ('Met-1'-linked) polyubiquitin chains to substrates and plays a key role in NF-kappa-B activation and regulation of inflammation (PubMed : 17006537, PubMed : 19136968, PubMed : 20005846, PubMed : 21455173, PubMed : 21455180, PubMed : 21455181, PubMed : 22863777, PubMed : 28189684, PubMed : 28481331). LUBAC conjugates linear polyubiquitin to IKBKG and RIPK1 and is involved in activation of the canonical NF-kappa-B and the JNK signaling pathways (PubMed : 17006537, PubMed : 19136968, PubMed : 20005846, PubMed : 21455173, PubMed : 21455180, PubMed : 21455181, PubMed : 22863777, PubMed : 28189684). Linear ubiquitination mediated by the LUBAC complex interferes with TNF-induced cell death and thereby prevents inflammation (PubMed : 21455173, PubMed : 28189684). LUBAC is 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 (PubMed : 20005846, PubMed : 27458237). The LUBAC complex is also involved in innate immunity by conjugating linear polyubiquitin chains at the surface of bacteria invading the cytosol to form the ubiquitin coat surrounding bacteria (PubMed : 28481331, PubMed : 34012115). LUBAC is not able to initiate formation of the bacterial ubiquitin coat, and can only promote formation of linear polyubiquitins on pre-existing ubiquitin (PubMed : 28481331). Recruited to the surface of bacteria by RNF213, which initiates the bacterial ubiquitin coat (PubMed : 34012115). The bacterial ubiquitin coat acts as an 'eat-me' signal for xenophagy and promotes NF-kappa-B activation (PubMed : 28481331, PubMed : 34012115). Together with OTULIN, the LUBAC complex regulates the canonical Wnt signaling during angiogenesis (PubMed : 23708998). RNF31 is required for linear ubiquitination of BCL10, thereby promoting TCR-induced NF-kappa-B activation (PubMed : 27777308). Binds polyubiquitin of different linkage types (PubMed : 23708998).
