Sorting nexins (SNX) represent a diverse family of proteins involved in crucial cellular processes, particularly the regulation of intracellular membrane trafficking and sorting. SNX proteins play a pivotal role in orchestrating the endocytic and recycling pathways within cells, ensuring the precise localization and transport of various membrane-bound cargo proteins. Structurally, SNX proteins are characterized by the presence of one or more phosphoinositide-binding domains, most notably the Phox homology (PX) domain, which enables their association with specific phospholipids in cellular membranes. SNX proteins act as molecular adaptors that interact with other cellular components, such as clathrin, to facilitate the formation of membrane vesicles and the selective sorting of cargo molecules. By recognizing distinct sorting signals in cargo proteins, SNX proteins contribute to the proper routing of cargo between different membrane compartments, including endosomes, lysosomes, the trans-Golgi network, and the plasma membrane. Moreover, SNX proteins can engage in intricate protein-protein interactions with other cellular factors, including GTPases, to modulate membrane dynamics and cellular responses. Sorting Nexin (SNX) Inhibitors are designed to interfere with the activity or interactions of SNX proteins within the cellular trafficking machinery. These inhibitors serve as valuable tools in research to dissect the roles of SNX proteins and their contributions to membrane dynamics and cargo sorting processes. Some SNX inhibitors may target the phosphoinositide-binding domains of SNX proteins, disrupting their membrane localization and impeding their ability to bind to specific lipids. Others may interfere with protein-protein interactions involving SNX proteins, preventing their association with cargo molecules, adaptors, or other regulatory factors.
