Focal adhesions: What's new inside

open access: yesDevelopmental Biology, 2006
The cytoplasmic side of focal adhesions is comprised of large molecular complexes that link transmembrane receptors, such as integrins, to the actin cytoskeleton and mediate signals modulating cell attachment, migration, proliferation, differentiation, and gene expression.

Unanchoring integrins in focal adhesions

open access: yesNature Cell Biology, 2012
Focal adhesions are large structures through which integrins and scaffold proteins link the actin cytoskeleton to the extracellular matrix. A detailed analysis of integrin dynamics now indicates that focal-adhesion-associated integrins constantly switch between active and immobilized, and unbound and free-diffusing states, with different fibronectin ...

Emerging S100A11 roles: Regulation of focal adhesion dynamics and mechanosensing

open access: yesCell Structure and Function
S100A11 is a small calcium-binding protein that has been studied in the context of growth regulation and membrane repair. However, it has recently been linked to the disassembly of focal adhesions.

The COOH terminus of the c-Abl tyrosine kinase contains distinct F- and G-actin binding domains with bundling activity [PDF]

open access: yes, 1994
The myristoylated form of c-Abl protein, as well as the P210bcr/abl protein, have been shown by indirect immunofluorescence to associate with F-actin stress fibers in fibroblasts. Analysis of deletion mutants of c-Abl stably expressed in fibroblasts maps

Studies of focal adhesion assembly

open access: yesBiochemical Society Transactions, 2008
Recent studies of some proteins involved in the formation of focal adhesions are described. These include fibronectin, integrins, talin, Dok1 and filamin. Emphasis is placed on features that facilitate regulated assembly of complexes; these include a modular construction and flexible regions that provide interaction sites whose affinity can be adjusted
