The USP4 (N-term) antibody is a tool used to detect the N-terminal region of Ubiquitin Specific Peptidase 4 (USP4), a deubiquitinating enzyme (DUB) involved in regulating protein stability and signaling pathways. USP4. a member of the ubiquitin-specific protease family, removes ubiquitin molecules from target proteins, counteracting ubiquitination-mediated degradation or modulation. It plays critical roles in diverse cellular processes, including DNA repair, immune response, Wnt/β-catenin signaling, and TGF-β pathways, and is implicated in cancer, neurodegeneration, and viral infections.
The antibody specifically recognizes epitopes near the N-terminus of USP4. enabling researchers to distinguish USP4 from other DUBs or its isoforms. It is commonly used in techniques like Western blotting, immunoprecipitation, and immunofluorescence to study USP4 expression, localization, and interactions. USP4 contains distinct structural domains, such as the catalytic USP domain and N-terminal regulatory regions that mediate substrate recognition or protein interactions. The N-terminal region targeted by this antibody may influence USP4’s enzymatic activity, substrate specificity, or binding partners, making it valuable for functional studies.
Research utilizing this antibody has contributed to understanding USP4’s role in diseases, particularly cancer, where it may act as an oncogene or tumor suppressor depending on context. Its applications extend to exploring therapeutic strategies targeting USP4 in conditions like inflammation or chemotherapy resistance.
