KBTBD13 Inhibitors

Inhibitors of KBTBD13 primarily target the ubiquitin-proteasome system and autophagy pathways, both of which are integral to protein degradation and turnover in cells. The ubiquitin-proteasome system is a pathway for degrading proteins that have been tagged with ubiquitin, a small regulatory protein. Inhibitors such as MG-132, Lactacystin, Bortezomib, and Thalidomide can disrupt this system, leading to altered protein degradation rates that may influence the function of KBTBD13. On the other hand, autophagy is a process that cells use to degrade and recycle cytoplasmic components. SMER3, Chloroquine, 3-MA, and NH4Cl are chemicals that can modulate this pathway, either by enhancing or inhibiting it. KBTBD13's function could be influenced by changes in autophagic processes due to the disruption caused by these compounds.

PYR-41 and MLN4924 (Pevonedistat) target the ubiquitination process more directly. PYR-41 is an inhibitor of the E1 ubiquitin-activating enzyme, while MLN4924 inhibits the NEDD8-activating enzyme. By impeding these enzymes, the ubiquitination of proteins that KBTBD13 may interact with or regulate could be altered. Lastly, Epoxomicin and Omuralide (a synonym for Lactacystin) are selective proteasome inhibitors that specifically target the degradation of misfolded proteins. Disruption of this process can lead to the accumulation of proteins that may normally be regulated by KBTBD13, indirectly affecting its role in the cell.
