The TRIP10 gene is located on chromosome 19 and is a protein-coding gene . The protein encoded by this gene is involved in the translocation of GLUT4 to the plasma membrane in response to insulin signaling . It also coordinates membrane tubulation with the reorganization of the actin cytoskeleton during endocytosis .
TRIP10 binds to lipids such as phosphatidylinositol 4,5-bisphosphate and phosphatidylserine, promoting membrane invagination and the formation of tubules . It also promotes CDC42-induced actin polymerization by recruiting WASL/N-WASP, which in turn activates the Arp2/3 complex . This actin polymerization may promote the fission of membrane tubules to form endocytic vesicles . Additionally, TRIP10 is required for the formation of podosomes, actin-rich adhesion structures specific to monocyte-derived cells .
TRIP10 has been identified as a biomarker for Huntington’s disease . It is also associated with Wiskott-Aldrich Syndrome, a rare genetic disorder that affects the immune system and blood clotting . The protein’s involvement in various signaling pathways, such as those mediated by Rho GTPases and vesicle-mediated transport, underscores its importance in cellular function and disease .
The recombinant form of TRIP10 is used in research to study its role in cellular processes and its involvement in diseases. Understanding the function and mechanism of TRIP10 can provide insights into potential therapeutic targets for diseases associated with this protein.
