Function
Integrin alpha-V/beta-3 (ITGAV:ITGB3) is a receptor for cytotactin, fibronectin, laminin, matrix metalloproteinase-2, osteopontin, osteomodulin, prothrombin, thrombospondin, vitronectin and von Willebrand factor. Integrin alpha-IIb/beta-3 (ITGA2B:ITGB3) is a receptor for fibronectin, fibrinogen, plasminogen, prothrombin, thrombospondin and vitronectin. Integrins alpha-IIb/beta-3 and alpha-V/beta-3 recognize the sequence R-G-D in a wide array of ligands. Integrin alpha-IIb/beta-3 recognizes the sequence H-H-L-G-G-G-A-K-Q-A-G-D-V in fibrinogen gamma chain. Following activation integrin alpha-IIb/beta-3 brings about platelet/platelet interaction through binding of soluble fibrinogen. This step leads to rapid platelet aggregation which physically plugs ruptured endothelial surface. Fibrinogen binding enhances SELP expression in activated platelets (By similarity). ITGAV:ITGB3 binds to fractalkine (CX3CL1) and acts as its coreceptor in CX3CR1-dependent fractalkine signaling (PubMed:23125415, PubMed:24789099). ITGAV:ITGB3 binds to NRG1 (via EGF domain) and this binding is essential for NRG1-ERBB signaling (PubMed:20682778). ITGAV:ITGB3 binds to FGF1 and this binding is essential for FGF1 signaling (PubMed:18441324). ITGAV:ITGB3 binds to FGF2 and this binding is essential for FGF2 signaling (PubMed:28302677). ITGAV:ITGB3 binds to IGF1 and this binding is essential for IGF1 signaling (PubMed:19578119). ITGAV:ITGB3 binds to IGF2 and this binding is essential for IGF2 signaling (PubMed:28873464). ITGAV:ITGB3 binds to IL1B and this binding is essential for IL1B signaling (PubMed:29030430). ITGAV:ITGB3 binds to PLA2G2A via a site (site 2) which is distinct from the classical ligand-binding site (site 1) and this induces integrin conformational changes and enhanced ligand binding to site 1 (PubMed:18635536, PubMed:25398877). ITGAV:ITGB3 acts as a receptor for fibrillin-1 (FBN1) and mediates R-G-D-dependent cell adhesion to FBN1 (PubMed:12807887). In brain, plays a role in synaptic transmission and plasticity. Involved in the regulation of the serotonin neurotransmission, is required to localize to specific compartments within the synapse the serotonin receptor SLC6A4 and for an appropriate reuptake of serotonin. Controls excitatory synaptic strength by regulating GRIA2-containing AMPAR endocytosis, which affects AMPAR abundance and composition (By similarity).

- Activity summary
Integrin beta 3 also known as ITGB3 beta 3 integrin or CD41/CD61 is a cell surface receptor that plays a role in cell adhesion and signal transduction. It is a member of the integrin family characterized by a heterodimer structure formed with an alpha subunit. This integrin has a molecular mass of approximately 88 kDa. Integrin beta 3 is expressed on platelets megakaryocytes and several other cell types such as endothelial cells and certain tumor cells.
- Biological function summary
Integrins serve as the mechanical link between the extracellular matrix and the cytoskeleton. Beta 3 integrin forms a complex with different alpha subunits most notably alpha IIb to function as a receptor for fibrinogen fibronectin and vitronectin. This receptor complex is essential for platelet aggregation and normal hemostasis. Dysregulation can lead to altered cellular responses impacting processes like immune response and tumor progression.
- Pathways
Integrin beta 3 participates in the signaling of outside-in and inside-out pathways that are fundamental in cellular dynamics. Of particular significance are the integrin-mediated signaling pathways and the TGF-beta signaling pathway which influence cellular proliferation and differentiation. Integrin beta 3 interacts with proteins such as talin and kindlin which are vital for activation and clustering of integrins during cell signaling processes.
- Associated diseases and disorders
Altered expression or function of integrin beta 3 is associated with bleeding disorders like Glanzmann's thrombasthenia where platelet aggregation is impaired. Additionally it plays a role in the progression of certain cancers due to its involvement in cell migration and invasion. The interaction of integrin beta 3 with proteins such as VEGF and MMPs is significant in the context of tumor angiogenesis and metastasis.
