Integrins are transmembrane receptors that help cell–cell and cell–extracellular matrix (ECM) adhesion. [3] Upon ligand binding, integrins activate signal transduction pathways that mediate cellular signals such as regulation of the cell cycle, organization of the intracellular cytoskeleton, and movement of new receptors to the cell membrane. [4]
True homologs of integrins exist in mammals, invertebrates, and some fungi but not in plant cells. Mammalian integrins are heterodimer transmembrane proteins that play a large role in bidirectional signal transduction. [1] As transmembrane proteins, integrins connect the extracellular matrix (ECM) to the plasma membrane of the animal cell. [1]
Ligand binding to the extracellular domain of integrins changes the protein's conformation, clustering it at the cell membrane to initiate signal transduction. Integrins lack kinase activity; hence, integrin-mediated signal transduction is achieved through a variety of intracellular protein kinases and adaptor molecules, the main coordinator ...

Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...

In addition to binding to ECM ligands, integrins are also receptive to autocrine and paracrine signals such as growth factors in the TGF-beta family. Chondrocytes have been shown to secrete TGF-b, and upregulate TGF-b receptors in response to mechanical stimulation; this secretion may be a mechanism for autocrine signal amplification within the ...
A more complex signal transduction pathway is the MAPK/ERK pathway, which involves changes of protein–protein interactions inside the cell, induced by an external signal. Many growth factors bind to receptors at the cell surface and stimulate cells to progress through the cell cycle and divide .
