The Emerging Role of OTUB2 in Diseases: From Cell Signaling Pathway to Physiological Function

Area of Science:

• Molecular Biology
• Biochemistry
• Cellular Signaling

Background:

• Otubain2 (OTUB2), a cysteine protease in the OTU family, possesses deubiquitinase activity.
• Cell signaling pathways are regulated by mechanisms like ubiquitination and phosphorylation.
• OTUB2's role in deubiquitinating key proteins in various signaling pathways is increasingly recognized.

Purpose of the Study:

• To comprehensively review the regulatory mechanisms of OTUB2 in different cell signaling pathways.
• To elucidate the connection between OTUB2 and cancer, focusing on DNA damage repair and immunity.
• To establish a theoretical foundation for future research on OTUB2 as a therapeutic target.

Main Methods:

• Literature review and analysis of existing research on OTUB2.
• Exploration of OTUB2's involvement in deubiquitination processes.
• Connecting OTUB2 function to cancer-related research areas like DNA damage repair and immunity.

Main Results:

• OTUB2 plays a role in deubiquitinating critical proteins within diverse cell signaling pathways.
• The precise impact of OTUB2 on human health and disease, particularly cancer, requires further investigation.
• OTUB2 is implicated in both normal physiological functions and the potential development of malignant diseases.

Conclusions:

• A thorough understanding of OTUB2's regulatory mechanisms is crucial for disease treatment strategies.
• OTUB2's involvement in DNA damage repair and immune responses highlights its significance in cancer research.
• This review provides a foundation for future studies targeting OTUB2 in oncological and other diseases.
