Integrin activation and internalization

Nettet2. mai 2024 · Integrins are transmembrane receptors and cell adhesion molecules, capable of bidirectional signaling as well. The functioning of integrins is not merely influenced by their gene expressional pattern, but also by their internalization, recycling and degradation rate, which forms a cycle. Nettet8. jul. 2024 · Integrin activation is essential for cell adhesion and for connecting the extracellular matrix to the actin cytoskeleton. Thus, inappropriate integrin activation has been linked to several diseases, including cancer. Recent insights demonstrate that the main fibrillar adhesion component tensin maintains β1-integrin active in these mature …
