Integrin β4 Activators

Common Integrin β4 Activators include, but are not limited to Retinoic Acid, all trans CAS 302-79-4, Lipopolysaccharide, E. coli O55:B5 CAS 93572-42-0, PMA CAS 16561-29-8, Dexamethasone CAS 50-02-2 and Fibronectin CAS 86088-83-7.

Integrin β4 (also known as ITGB4) is a protein that, in humans, is encoded by the ITGB4 gene. It's a component of the hemidesmosomes and plays an important role in cell adhesion and migration. The expression of integrin β4 can be influenced by various factors. Integrin β4 Activators belong to a class of molecules that modulate the activity of the integrin β4 protein. Integrins are transmembrane receptors that play a critical role in cell adhesion and signaling. These receptors are essential for various cellular processes, including cell migration, tissue development, and the immune response. Integrin β4, in particular, is a member of the integrin family that is primarily found in epithelial cells. It is notable for its role in the formation and maintenance of epithelial tissues, such as the skin and the lining of various organs, including the lungs and the digestive tract.

Integrin β4 Activators are substances or factors that can influence the activity or expression of the integrin β4 protein. These activators can impact various cellular functions, especially those related to cell adhesion, migration, and tissue organization. Integrin β4 is particularly important in maintaining the structural integrity of epithelial tissues. In the skin, for example, it plays a crucial role in the formation of hemidesmosomes, which are specialized cell adhesion structures that anchor the epidermis (the outermost layer of skin) to the underlying basement membrane. Disruptions in integrin β4 function can lead to skin disorders and can compromise the barrier function of the skin. Furthermore, integrin β4 has been implicated in cancer progression, as changes in its activity can affect cell adhesion, motility, and invasion, which are hallmark features of cancer metastasis. Therefore, the study of Integrin β4 Activators is essential in understanding the regulation of integrin-mediated processes, which has implications for both normal tissue development and various disease states, including cancer.
