lamininreceptor

Laminin receptors are a family of cell surface proteins that bind to laminin, a major component of the extracellular matrix. They play crucial roles in various cellular processes, including cell adhesion, migration, and differentiation. Laminin receptors are classified into three main groups based on their structure and function: integrins, dystroglycans, and merlin. Integrins are heterodimeric proteins that form a complex with laminin and other extracellular matrix proteins, facilitating cell adhesion and signaling. Dystroglycans, including α-dystroglycan and β-dystroglycan, are transmembrane proteins that link laminin to the actin cytoskeleton, contributing to cell adhesion and stability. Merlin, also known as ezrin, radixin, and moesin (ERM) protein, is a cytoskeletal protein that interacts with laminin receptors to regulate cell shape and motility. Dysfunction of laminin receptors has been implicated in various diseases, including muscular dystrophies, cancer, and neurodegenerative disorders. Understanding the mechanisms by which laminin receptors regulate cellular processes is essential for developing therapeutic strategies for these conditions.
