Integrin alpha 5 beta 1 Protein, Human (HEK293, His-Avi)

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. Integrin alpha 5 beta 1 Protein, Human (HEK293, His-Avi) is a recombinant protein dimer complex containing human-derived Integrin alpha 5 beta 1 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. Integrin alpha 5 beta 1 Protein, Human (HEK293, His-Avi), has molecular weight of 100-140 kDa.

The Integrin alpha-5/beta-1 protein (ITGA5:ITGB1) functions as a versatile receptor with diverse ligand interactions. Recognizing the R-G-D sequence in its ligands, ITGA5:ITGB1 serves as a receptor for fibronectin and fibrinogen, mediating cell adhesion through distinct binding sites. Notably, it binds to PLA2G2A at a site separate from its classical ligand-binding site, inducing conformational changes that enhance ligand binding. Additionally, ITGA5:ITGB1 acts as a receptor for fibrillin-1 (FBN1), facilitating R-G-D-dependent cell adhesion. It is also a receptor for fibronectin (FN1), enabling R-G-D-dependent cell adhesion to FN1. Furthermore, ITGA5:ITGB1 serves as a receptor for IL1B, playing a crucial role in IL1B signaling. In the context of microbial infection, ITGA5:ITGB1 acts as a receptor for Human metapneumovirus, highlighting its involvement in pathogen recognition. Moreover, ITGA5:ITGB3 acts as a receptor for soluble CD40LG, playing a vital role in CD40/CD40LG signaling. This broad spectrum of ligand interactions underscores the multifunctionality of ITGA5:ITGB1 in cellular processes and signaling pathways.
