CD63 protein acts as a receptor for TIMP1, activating cell signaling pathways and promoting cell survival. It plays a key role in integrin signaling, leading to activation of AKT, FAK/PTK2, and MAP kinases. CD63 Protein, Human/Cynomolgus (HEK293, N-His) is the recombinant human-derived CD63 protein, expressed by HEK293 , with N-6*His labeled tag.
