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. 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.

Supplementary info
This supplementary information is collated from multiple sources and compiled automatically.
- Activity summary
The OTUB1 protein also known as OTU domain-containing ubiquitin aldehyde-binding protein 1 plays an important role in the removal of ubiquitin from proteins. This process is important for regulating protein stability and function within the cell. OTUB1 has a mass of approximately 32 kDa and is expressed ubiquitously across various tissues indicating its essential nature in cellular functions.
- Biological function summary
OTUB1 functions as a deubiquitinating enzyme that cleaves ubiquitin from substrates influencing various cellular processes. It acts independently or as part of larger protein complexes. By controlling protein degradation pathways OTUB1 impacts protein turnover and cellular homeostasis. Interactions with other proteins allow OTUB1 to exert influence on different signaling pathways and cellular stress responses.
- Pathways
OTUB1 holds a significant position in the regulation of the ubiquitin-proteasome system and DNA damage repair pathway. It closely interacts with proteins such as UBE2N affecting the DNA damage response. Additionally OTUB1 regulates processes through modulating pathways like NF-kB by interacting with and stabilizing specific protein factors involved.
- Associated diseases and disorders
OTUB1’s function connects it to various pathological states like cancer and neurodegenerative diseases. Aberrant expression or mutations in OTUB1 can lead to disruptions in cell cycle regulation and apoptosis contributing to oncogenesis. In the context of neurodegenerative diseases OTUB1 is related to tau stabilization with proteins such as HSP90 playing a role in the same regulatory mechanisms highlighting its relevance in these disorders.
