**Background of Recombinant Human USP50 Protein**
Ubiquitin-specific protease 50 (USP50), a member of the ubiquitin-specific protease (USP) family, plays a critical role in regulating protein stability and cellular processes through deubiquitination. This enzymatic activity enables USP50 to remove ubiquitin chains from target proteins, thereby modulating their degradation, localization, or interactions. Unlike many USPs, USP50 is notable for its unique structural features, including a divergent catalytic domain and extended N-terminal region, suggesting specialized substrate recognition or regulatory mechanisms.
Recombinant human USP50 protein is typically expressed in vitro using bacterial or mammalian systems, enabling studies of its biochemical properties, substrate specificity, and interaction networks. Research highlights its involvement in DNA damage response, cell cycle regulation, and immune signaling. For example, USP50 interacts with components of the Fanconi anemia pathway, implicating it in genome maintenance. Additionally, its potential role in viral infection responses, such as modulating host antiviral defenses, has drawn interest.
Dysregulation of USP50 has been linked to diseases, including cancers and neurodegenerative disorders, though its exact mechanistic contributions remain under investigation. Recombinant USP50 serves as a vital tool for uncovering its physiological and pathological functions, as well as for screening therapeutic agents targeting deubiquitinating enzymes. Ongoing studies aim to clarify its regulatory networks and validate its candidacy for diagnostics or drug development.
