integrin alpha5-beta1 complex
Definition
Target type: cellularcomponent
An integrin complex that comprises one alpha5 subunit and one beta1 subunit. [PMID:12297042]
The integrin alpha5-beta1 complex is a transmembrane receptor protein that plays a crucial role in cell adhesion, migration, and signaling. It is composed of two subunits, alpha5 and beta1, both of which are type I transmembrane proteins. The extracellular domain of the alpha5 subunit binds to the Arg-Gly-Asp (RGD) sequence present in various extracellular matrix (ECM) proteins, particularly fibronectin. The beta1 subunit, on the other hand, interacts with other integrin subunits and with intracellular signaling molecules. The two subunits associate non-covalently through their transmembrane domains, forming a heterodimer. The cytoplasmic domains of both alpha5 and beta1 interact with a variety of intracellular proteins, including focal adhesion kinase (FAK), talin, and paxillin. These interactions are essential for the formation of focal adhesions, which are specialized structures that connect the ECM to the actin cytoskeleton. The integrin alpha5-beta1 complex is involved in a wide range of cellular processes, including cell spreading, migration, proliferation, and differentiation. Its dysfunction has been linked to various diseases, such as cancer metastasis, cardiovascular disease, and fibrosis.'
