Integrin α5 also known as CD49e, ITGA5 is a member of the integrin alpha chain family. Integrin α5 plays a crucial role in cell adhesion and is primarily located on the cell surface, where Integrin α5 forms heterodimers with the β1 subunit to create the α5β1 integrin receptor. This receptor is essential for binding to extracellular matrix components like fibronectin, which is vital for various cellular processes, including tissue repair, cell migration, and differentiation. Integrin α5 on the cell surface facilitates interaction with the extracellular matrix, promoting cellular signaling pathways that influence cell behavior and function. Furthermore, Integrin α5′s ability to cluster and interact with other integrins enhances signaling capacity, making Integrin α5 a key player in the regulation of cellular responses to the extracellular environment.
