Entrez Gene Summary for OTUB1 Gene

  • The product of this gene is a member of the OTU (ovarian tumor) superfamily of predicted cysteine proteases. The encoded protein is a highly specific ubiquitin iso-peptidase, and cleaves ubiquitin from branched poly-ubiquitin chains but not from ubiquitinated substrates. It interacts with another ubiquitin protease and an E3 ubiquitin ligase that inhibits cytokine gene transcription in the immune system. It is proposed to function in specific ubiquitin-dependent pathways, possibly by providing an editing function for polyubiquitin chain growth. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

GeneCards Summary for OTUB1 Gene

OTUB1 (OTU Deubiquitinase, Ubiquitin Aldehyde Binding 1) is a Protein Coding gene. Among its related pathways are Cell Cycle / Checkpoint Control and Protein Stability. GO annotations related to this gene include ubiquitin protein ligase binding and ubiquitin binding. An important paralog of this gene is OTUB2.

UniProtKB/Swiss-Prot for OTUB1 Gene

  • Hydrolase that can specifically remove Lys-48-linked conjugated ubiquitin from proteins and plays an important regulatory role at the level of protein turnover by preventing degradation. Regulator of T-cell anergy, a phenomenon that occurs when T-cells are rendered unresponsive to antigen rechallenge and no longer respond to their cognate antigen. Acts via its interaction with RNF128/GRAIL, a crucial inductor of CD4 T-cell anergy. Isoform 1 destabilizes RNF128, leading to prevent anergy. In contrast, isoform 2 stabilizes RNF128 and promotes anergy. Surprisingly, it regulates RNF128-mediated ubiquitination, but does not deubiquitinate polyubiquitinated RNF128. Deubiquitinates estrogen receptor alpha (ESR1). Mediates deubiquitination of Lys-48-linked polyubiquitin chains, but not Lys-63-linked polyubiquitin chains. Not able to cleave di-ubiquitin. Also capable of removing NEDD8 from NEDD8 conjugates, but with a much lower preference compared to Lys-48-linked ubiquitin

  • Plays a key non-catalytic role in DNA repair regulation by inhibiting activity of RNF168, an E3 ubiquitin-protein ligase that promotes accumulation of Lys-63-linked histone H2A and H2AX at DNA damage sites. Inhibits RNF168 independently of ubiquitin thioesterase activity by binding and inhibiting UBE2N/UBC13, the E2 partner of RNF168, thereby limiting spreading of Lys-63-linked histone H2A and H2AX marks. Inhibition occurs by binding to free ubiquitin: free ubiquitin acts as an allosteric regulator that increases affinity for UBE2N/UBC13 and disrupts interaction with UBE2V1. The OTUB1-UBE2N/UBC13-free ubiquitin complex adopts a configuration that mimics a cleaved Lys48-linked di-ubiquitin chain

    Size:
    271 amino acids
    Molecular mass:
    31284 Da
    Quaternary structure:
    • Isoform 1 and isoform 2 interact with RNF128. Isoform 1 forms a ternary complex with RNF128 and USP8. Isoform 1 interacts with the C-terminal UCH catalytic domain of USP8. Isoform 2 does not associate with USP8. Interacts with FUS, ESR1 and GNB2L1/RACK1. Interacts with UBE2N/UBC13.
    Miscellaneous:
    • In the structure described by PubMed:18954305, the His-265 active site of the catalytic triad is located too far to interact directly with the active site Cys-91. A possible explanation is that OTUB1 is in inactive conformation in absence of ubiquitin and a conformation change may move His-265 in the proximity of Cys-91 in presence of ubiquitin substrate

Function for OTUB1 Gene

Molecular function for OTUB1 Gene

UniProtKB/Swiss-Prot CatalyticActivity: Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal).
UniProtKB/Swiss-Prot EnzymeRegulation: By free ubiquitin: binding of free ubiquitin triggers conformational changes in the OTU domain and formation of a ubiquitin-binding helix in the N-terminus, promoting binding of the conjugated donor ubiquitin in UBE2N/UBC13 to OTUB1.
UniProtKB/Swiss-Prot Function: Hydrolase that can specifically remove Lys-48-linked conjugated ubiquitin from proteins and plays an important regulatory role at the level of protein turnover by preventing degradation. Regulator of T-cell anergy, a phenomenon that occurs when T-cells are rendered unresponsive to antigen rechallenge and no longer respond to their cognate antigen.
