Integrins are cell surface receptors that mediate cell adhesion to the extracellular matrix, while cadherins are cell adhesion molecules that facilitate cell-cell adhesion. Integrins bind to extracellular matrix proteins, while cadherins bind to other cadherins on adjacent cells. Integrins are involved in signaling pathways that regulate cell migration and proliferation, while cadherins are important for maintaining tissue structure and organization.
Cadherins are cell adhesion proteins that mediate calcium-dependent cell-cell adhesion, while integrins are cell adhesion receptors that mediate cell-matrix adhesion. Cadherins are involved in homophilic interactions between cells of the same type, while integrins are involved in heterophilic interactions between cells and the extracellular matrix. Cadherins form adherens junctions, while integrins form focal adhesions.
Integrin proteins typically do not interact with pilin for internalization in mammalian cells. Integrins are primarily involved in cell adhesion and signaling, while pilin is a structural subunit of pili used by bacteria for adhesion to host cells. The internalization of pilin is usually mediated by other bacterial or host cell receptors and mechanisms.

For cytokinesis, essentials include actin filaments forming a contractile ring, myosin motor proteins for contraction, and Rho GTPases regulating cytoskeletal dynamics. In amoeboid movement, actin polymerization at the leading edge, myosin contraction at the rear, and integrin-mediated adhesion to the substrate are key. Changes in cell shape involve rearrangement of actin filaments, microtubules guiding structural changes, and cell adhesion molecules mediating cell-cell interactions.
Many cells bind to components of the extracellular matrix. This cell-to-ECM adhesion is regulated by specific cell surfacecellular adhesion molecules (CAM) known as integrins. Integrins are cell surface proteins that bind cells to ECM structures, such as fibronectin and laminin, and also to integrin proteins on the surface of other cells. Fibronectins bind to ECM macromolecules and facilitate their binding to transmembrane integrins. The attachment of fibronectin to the extracellular domain initiates intracellular signaling pathways as well as association with the cellular cytoskeleton via a set of adaptor molecules such as actin.[2]

The divalent cation magnesium ion (Mg^2+) is required to maintain the proper integrin structure and facilitate ligand binding. Magnesium ions help stabilize the integrin conformation and promote interactions with ligands to facilitate cell adhesion and signaling.
yup. T shaped with blobs on the end. Have you googled integrin?

Yes, that is why they call it the fluid mosaic bilayer. All the integrin proteins and cholesterol are constantly moving position in the bilayer, except when they are anchored.

Hemidesmosomes are cell junctions that anchor epithelial cells to the basement membrane in tissues. They are composed of integrin proteins and intermediate filaments such as keratin. Hemidesmosomes help provide structural support and stability to tissues subjected to mechanical stress.
