It is widely used as a **biomarker for EV identification and isolation**. ==== Structure and Function ==== * Four transmembrane domains * Localized in late endosomes, lysosomes, and exosomes * Involved in: * Vesicle formation and trafficking * Protein sorting * Cell adhesion and immune modulation ==== In EV Engineering ==== CD63 is often used as a **molecular scaffold** for displaying functional tags or facilitating **selective cargo loading** in synthetic or engineered EVs, such as in the [[engineering_cd63_evs|E-NoMi system]]. cd63.txt Last modified: 2025/06/18 09:21by administrador
