Dda1 Inhibitors

Chemical inhibitors of Dda1 target various aspects of the protein's role in cellular processes, primarily focusing on the ubiquitin-proteasome system. The proteasome is a complex that degrades ubiquitinated proteins, a pathway where Dda1 is implicated. Compounds such as Velcade and Bortezomib directly inhibit the 26S proteasome, leading to the accumulation of proteins that are typically regulated by Dda1. This accumulation effectively reduces Dda1's ability to facilitate the normal turnover and degradation of these proteins. Similarly, MG-132 serves as a reversible inhibitor of the proteasome, impacting the protein networks and interactions that Dda1 is involved in, leading to a decrease in its functional capacity. Lactacystin, as another proteasome inhibitor, causes an increase in polyubiquitinated proteins, which indirectly alters the functional role of Dda1 in managing these proteins.

Further along this line, Epoxomicin, Carfilzomib, and Oprozomib bind to and inhibit proteasome activity, which disrupts the protein degradation pathway, a critical process that Dda1 is associated with. This disruption leads to an indirect inhibition of Dda1, as it cannot perform its role effectively when proteasome activity is compromised. Marizomib also inhibits the proteasome, thereby affecting the protein homeostasis that Dda1 is part of, while Ixazomib's selective inhibition of the 20S proteasome impacts protein degradation in a similar manner. Delanzomib inhibits the proteasome, affecting pathways that Dda1 utilizes for protein regulation. Each of these chemicals, by targeting the ubiquitin-proteasome system, indirectly but effectively hinders Dda1's role in protein regulation and turnover.
