Integrin alpha 2B beta 3 Protein, Mouse (HEK293, His)

Customer Review

Based on 1 Customer Validation

Integrin α-IIb/β-3 is a multifunctional receptor that recognizes multiple ligands and plays a key role in platelet function and hemostasis. It binds fibronectin, fibrinogen, plasminogen, prothrombin, thrombospondin and vitronectin via the RGD sequence, specifically recognizing the HHLGGGAKQAGDV sequence in fibrinogen. Integrin alpha 2B beta 3 Protein, Mouse (HEK293, His) is a recombinant protein dimer complex containing mouse-derived Integrin alpha 2B beta 3 protein, expressed by HEK293 , with C-His labeled tag. Integrin alpha 2B beta 3 Protein, Mouse (HEK293, His), has molecular weight of 90-113 kDa.

Description

Integrin α-IIb/β-3 is a multifunctional receptor that recognizes multiple ligands and plays a key role in platelet function and hemostasis. It binds fibronectin, fibrinogen, plasminogen, prothrombin, thrombospondin and vitronectin via the RGD sequence, specifically recognizing the HHLGGGAKQAGDV sequence in fibrinogen. Integrin alpha 2B beta 3 Protein, Mouse (HEK293, His) is a recombinant protein dimer complex containing mouse-derived Integrin alpha 2B beta 3 protein, expressed by HEK293 , with C-His labeled tag. Integrin alpha 2B beta 3 Protein, Mouse (HEK293, His), has molecular weight of 90-113 kDa.

Background

The Integrin alpha-IIb/beta-3 protein is a multifaceted receptor with broad ligand recognition capabilities, including binding to fibronectin, fibrinogen, plasminogen, prothrombin, thrombospondin, and vitronectin through the R-G-D sequence. Specifically, it recognizes the H-H-L-G-G-G-A-K-Q-A-G-D-V sequence in the fibrinogen gamma chain. Upon activation, Integrin alpha-IIb/beta-3 facilitates platelet-platelet interactions by binding soluble fibrinogen, leading to rapid platelet aggregation that forms a physical plug on the ruptured endothelial cell surface. Structurally, it forms a heterodimer, with the alpha subunit consisting of a heavy and a light chain linked by a disulfide bond, and the alpha-IIb subunit associates with beta-3. Additionally, Integrin alpha-IIb/beta-3 directly interacts with RNF181, and its cytoplasmic tail region interacts with CIB1, CIB2, CIB3, and CIB4 in a calcium and magnesium-dependent manner. Furthermore, its interaction with PPIA/CYPA is ROS and PPIase activity-dependent and is increased in the presence of thrombin. This diverse range of interactions highlights the integral role of Integrin alpha-IIb/beta-3 in platelet function and hemostasis.
