Recombinant Saccharomyces cerevisiae RPN13 Protein ，His & SUMO

RPN13, a pivotal component of the 26S proteasome, plays a critical role in the regulation of protein degradation, which is essential for maintaining cellular homeostasis and regulating various cellular processes, including cell cycle progression, apoptosis, and stress responses. Recent studies have highlighted the involvement of RPN13 in the recognition and processing of ubiquitinated substrates, thus ensuring that damaged or misfolded proteins are efficiently targeted for degradation. Its unique structure, featuring a ubiquitin-binding domain, allows RPN13 to interact directly with ubiquitin chains, facilitating the delivery of substrates to the proteasome. Furthermore, aberrations in RPN13 expression or function have been implicated in several diseases, including cancer and neurodegenerative disorders, making it an attractive target for therapeutic interventions. The recombinant expression of RPN13 not only aids in the elucidation of its biochemical properties and interaction mechanisms but also enables the development of potential inhibitors that could modulate its activity in pathological conditions. Investigating RPN13 as a recombinant protein presents a valuable opportunity to deepen our understanding of proteasomal regulation and to explore its therapeutic potential in enhancing proteostasis and targeting diseases associated with proteasome dysfunction.
