Collagen-induced platelet activation - ScienceDirect

WebJan 2, 2024 · GPVI-collagen interaction. GPVI is the major signaling receptor for collagen. Collagen binds to the D1 domain in GPVI through a glycine-proline-hydroxyproline (GPO) sequence, with helical peptides based on this sequence, known as collagen-related peptides (CRPs), mimicking collagen-induced platelet activation. WebSubsequently, GPVI binds to collagen, leading to integrin α2β1 activation.
