VPS13C Inhibitors

VPS13C inhibitors belong to a class of chemical compounds that have garnered attention in the fields of molecular biology and pharmacology due to their ability to modulate specific cellular processes. VPS13C, or Vacuolar Protein Sorting 13 Homolog C, is a large multi-domain protein that primarily resides on the surface of membrane-bound organelles known as membrane contact sites (MCS). These sites are critical for the exchange of lipids and other molecules between organelles, and they play a crucial role in maintaining cellular homeostasis. VPS13C is specifically localized to MCS between the endoplasmic reticulum (ER) and other organelles, and it is involved in lipid transport and membrane tethering at these contact sites. VPS13C inhibitors are designed to interact with the active site or binding domain of the VPS13C protein, effectively inhibiting its function and influencing cellular processes dependent on VPS13C-mediated lipid transport and membrane contact site formation.

Structurally, VPS13C inhibitors are engineered to selectively target the active site or binding domains of VPS13C, ensuring high specificity for this particular multi-domain protein. By inhibiting VPS13C, these compounds may disrupt its role in mediating lipid transport and membrane tethering at ER contact sites, leading to alterations in lipid homeostasis and membrane dynamics within cells. The study of VPS13C inhibitors is of significant interest to researchers as it provides insights into the regulatory mechanisms governing essential cellular functions related to lipid metabolism, organelle interactions, and the maintenance of cellular structure and function. This knowledge contributes to our understanding of basic cell biology and may have implications in various research areas, including cellular physiology, membrane biology, and the molecular basis of diseases associated with dysregulated lipid transport and membrane contact site dysfunction.
