Function

SLB2_DEIAC Agglucetin specifically causes platelet aggregation and surface exposure of integrin alpha-IIb/beta-3 with a GPIb-(GP1BA-) dependent manner in washed platelets. It binds to human platelets in a saturable manner, and its binding is specifically blocked by anti-GP Ib mAb. It regulates endothelial cell survival and promotes angiogenesis by activating integrin alpha-v/beta-3 signaling through FAK/phosphatidylinositol 3-kinase (PI3K)/Akt pathway.^{[1] [2]}
