ITGA5 is a multifunctional receptor that interacts with multiple ligands such as fibronectin, fibrinogen, PLA2G2A, fibrillin-1 (FBN1), IL1B, human metapneumovirus, and soluble CD40LG. ITGA5 recognizes RGD sequences and mediates cell adhesion through different binding sites. ITGA5 Protein, Human (HEK293, His) is the recombinant human-derived ITGA5 protein, expressed by HEK293 , with C-6*His labeled tag.
