integrin alphav-beta1 complex
Definition
Target type: cellularcomponent
An integrin complex that comprises one alphav subunit and one beta1 subunit. [PMID:12297042]
The integrin alphav-beta1 complex, also known as the vitronectin receptor, is a transmembrane protein that plays a crucial role in cell adhesion, migration, and signaling. It is a heterodimer composed of two subunits: alphav and beta1. Each subunit has a large extracellular domain that interacts with extracellular matrix (ECM) proteins, a transmembrane domain that anchors the complex to the plasma membrane, and a short cytoplasmic domain that interacts with intracellular signaling molecules. The alphav subunit contains an inserted domain, known as the I-domain, which binds to the RGD motif found in many ECM proteins, including vitronectin, fibronectin, and fibrinogen. The beta1 subunit also contains an I-domain, which plays a role in binding to collagen. The alphav-beta1 complex can form distinct interactions with ECM proteins depending on its conformation and the presence of other proteins. The complex is also known to interact with various cell-surface receptors, including growth factor receptors, and intracellular signaling proteins, such as focal adhesion kinase (FAK) and Src kinases. These interactions contribute to its role in cell adhesion, migration, and signaling pathways, which are essential for cell growth, differentiation, and development.'
