Q-Peptide
0 ImagesQ-Peptide is an angiopoietin-1 derived peptide (QHREDGS). Q-Peptide interacts with β1-integrin, binds to integrins on the surface of osteoblasts, and serves as an acyl donor substrate for Streptomyces mobaraensis transglutaminase. Q-Peptide activates Akt, MAPKp42/44, ILK, ERK1/2, and downregulates caspase-3/7. Q-Peptide inhibits cell apoptosis, enhances cell adhesion and migration, and promotes osteoblast differentiation, bone matrix deposition and mineralization. Q-Peptide can be used in studies related to myocardial infarction, bone regeneration, diabetic wound repair and human induced pluripotent stem cells.
