CD63 is involved in multiple cellular processes. It plays a crucial role in endocytosis and exocytosis, particularly in the trafficking of proteins and lipids. The protein is also essential in the formation and function of multivesicular bodies (MVBs) and exosomes, which are involved in intercellular communication and waste removal. Additionally, CD63 participates in the regulation of cell adhesion and migration, impacting processes such as metastasis in cancer.
