Ubiquitin-Specific Proteases: Players in Cancer Cellular Processes

Area of Science:

• Biochemistry
• Molecular Biology
• Oncology

Background:

• Ubiquitination is a crucial post-translational modification (PTM) regulating protein function, localization, and turnover.
• Deubiquitinating enzymes (DUBs) reverse ubiquitination, impacting ubiquitin dynamics.
• Ubiquitin-specific proteases (USPs) are the largest DUB family, implicated in diverse cellular processes.

Purpose of the Study:

• To review the multifaceted cellular functions of USPs in cancer development and progression.
• To explore the involvement of USPs in critical pathways like cell cycle regulation and DNA damage repair.
• To summarize current therapeutic strategies targeting USP inhibition for cancer treatment.

Main Methods:

• Literature review focusing on ubiquitin-specific proteases (USPs) and their roles in carcinogenesis.
• Analysis of studies investigating USP involvement in cell cycle, DNA repair, chromatin remodeling, and signaling pathways.
• Compilation of information on existing and emerging therapies targeting USP inhibitors.

Main Results:

• USPs play significant roles in cell cycle control, DNA damage repair, and chromatin remodeling.
• Dysregulation of USP activity is linked to the development and progression of various cancers.
• Targeting USP activity presents a promising avenue for novel cancer therapies.

Conclusions:

• USPs are critical regulators of cellular processes and are frequently implicated in cancer.
• Inhibition of specific USPs holds therapeutic potential for treating diverse malignancies.
• Further research into USP functions and targeted inhibitors is warranted for advancing cancer treatment.
