A number of integrin-associated proteins, including talin, parvin, filamin, α-actinin, and tensin, have actin-binding domains. However, it is not yet clear whether the primary function of these domains at the integrin junction is to bind to actin or to other proteins. Introduction to integrin and its structure Integrins are proteins that function mechanically, by attaching the cell cytoskeleton to the extracellular matrix (ECM), and biochemically, by sensing whether adhesion has occurred.

Structural and functional studies suggest that integrins can exist in different ligand affinity states – low, intermediate and high (reviewed in).

They are commonly found at the ventral surface of cells in 2-dimensional tissue culture and can be envisioned as the feet of the cell, which function as interactive information interfaces between cells and 2003-05-15 · Integrin receptors connect the extracellular matrix to the actin cytoskeleton. This interaction can be viewed as a cyclical liaison, which develops again and again at new adhesion sites only to cease at sites of de-adhesion. 2019-10-28 · α M β 2 integrin (complement receptor 3) is a major receptor for phagocytosis in macrophages. In other contexts, integrins’ activities and functions are mechanically linked to actin dynamics 2006-04-04 · The present studies asked whether integrin-driven changes in spine actin polymerization can account for the rapid phase of LTP and, by inference, memory consolidation. This prediction would require that the changes occur quickly, have a threshold comparable with that for the production of stable LTP, be vulnerable to disruption for several minutes, and then, after 30–60 min, become resistant to further manipulation.

Recent excellent reviews on various aspects of integrins Abstract.The integrin family of extracellular matrix receptors regulates many aspects of cell life, in particular cell adhesion and migration. These two processes depend on organization of the actin cytoskeleton into adhesive and protrusive organelles in response to extracellular signals. Integrins are important switch points for the spatiotemporal control of actin-based motility in higher 43 paraffin-embedded, formalin-fixed lung tissue sections were immunostained for five molecules implicated in the pathogenesis of the fibrosis: α-smooth muscle actin (αSMA), αvβ6 integrin, pro-surfactant protein C (SP-C), hepatocyte growth factor (HGF) and tenascin-C (TenC).
