OTUB2 also known as OTU domain-containing ubiquitin aldehyde-binding protein 2 is an enzyme that acts mechanically as a deubiquitinating enzyme. It has a molecular mass of approximately 31 kDa. OTUB2 regulates ubiquitin signaling by cleaving ubiquitin from ubiquitinated proteins. This protein is expressed in various tissues with high expression in the liver and heart. It plays a role in modulating protein degradation and cellular signaling pathways.
Biological function summary
This protein influences cellular processes by interacting with ubiquitin-conjugating enzymes. OTUB2 often joins complexes that include ubiquitin-proteasome machinery components. Through these interactions it controls protein stability and degradation impacting cell cycle progression and DNA damage response. OTUB2's activity is essential for maintaining protein homeostasis which affects how cells respond to stress and changes in their environment.
Pathways
OTUB2 plays roles in the ubiquitin-proteasome and DNA repair pathways. In these pathways its interaction with other proteins like UBC13 and RAD51 is important for its function. These interactions help repair DNA damage and modulate the immune response. By regulating the stability of key signaling proteins OTUB2 ensures proper pathway function and cellular homeostasis.
OTUB2 connects to cancer and neurodegenerative diseases. In cancer its regulatory function on protein degradation affects tumor progression and resistance to therapy. With neurodegenerative diseases altered OTUB2 activity can disrupt protein homeostasis leading to accumulation of misfolded proteins. Interactions with proteins such as p53 in cancer and tau in neurodegenerative disorders link OTUB2 to disease mechanisms influencing therapeutic approaches and drug development strategies.
