Descrizione

Descrizione generale

E3 ubiquitin-protein ligase RNF31 (UniProt Q96EP0; also known as HOIL-1-interacting protein, HOIP, RING finger protein 31, Zinc in-between-RING-finger ubiquitin-associated domain protein) is encoded by the RNF31 (also known as ZIBRA) gene (Gene ID 55072) in human. HOIP is a RING-between-RING (RBR) family E3 ubiquitin ligase and the only enzyme known to catalyze linear-ubiquitin-chain conjugation. HOIP functions as the primary E3 Ub ligase of the immune signaling regulatory complex LUBAC (linear-ubiquitin-chain assembly complex) composed of heme-oxidized IRP2 ubiquitin ligase-1 (HOIL-1L), HOIP, and SHANK-associated RH domain interactor (Sharpin). RBR ligases often exist in autoinhibited conformations and require protein-protein interactions or posttranslational modifications to induce a conformational change for activation. Disruption of HOIP and HOIL-1L interaction in activated B cell-like (ABC) subtype of diffuse large B-cell lymphoma (DLBCL) induces DLBCL death as a result of decreased NF-κB activation due to HOIP inactivation. On the other hand, HOIP K1056R mutant is resistant to inactivation by TLR4 stimulation-induced HOIP K1056 ubiquitination. Human HOIP is a 1072-a.a. protein that contains a polyUb-binding region (a.a. 1-485), a ubiquitin-associated or UBA domain (a.a. 564-615) that mediates HOIL-1L/RBCK1 interactioin, and a C-terminal linear-ubiquitin-chain-determining domain or LDD domain (a.a. 910-1072). In addition, HOIP conatins three RanBP2-type Zinc fingers (a.a. 299-329, 350-379, 409-438), two RING-type Zinc fingers (a.a. 699-747 and 860-909), and one IBR-type Zinc fingers (a.a. 779-841).

Specificità

Clone 1CB2 detected a ~120 kDa target band only in parental, but not HOIP-knock, Jurkat cells. Clone 1CB2 targets an epitope within the C-terminal LDD domain present in all three human HOIP (RNF31) spliced isoforms reported by UniProt (Q96EP0).

Immunogeno

GST-tagged recombinant human HOIP (RNF31) LDD domain.
