VCP Activators

VCP (Valosin-containing protein) activators represent a distinctive chemical class within the realm of small molecules that interact with specific cellular proteins. VCP, also known as p97 or CDC48, is an essential enzyme belonging to the AAA+ (ATPases associated with diverse cellular activities) superfamily. This enzyme plays a pivotal role in various cellular processes, particularly in protein homeostasis and quality control mechanisms. VCP acts as a hexameric ATPase, utilizing the energy from ATP hydrolysis to unfold and extract proteins from multi-subunit complexes or cellular membranes. VCP activators are a class of compounds designed to modulate the activity of this enzyme, thereby influencing its role in diverse cellular functions.

The chemical structures of VCP activators are diverse, but they share a common objective: to enhance VCP's ATPase activity and promote its function as a molecular machine involved in protein degradation, membrane trafficking, and the disassembly of protein complexes. These compounds often target specific domains within the VCP enzyme, allosterically promoting ATP hydrolysis and, consequently, accelerating its unfolding and extraction functions. As a result, VCP activators can impact cellular processes such as endoplasmic reticulum-associated degradation (ERAD), ubiquitin-proteasome system-mediated protein degradation, and autophagy, all of which are crucial for maintaining cellular homeostasis.
