Focal adhesion kinase.   (Site not responding. Last check: 2007-10-28) Focal adhesions are found at the cell membrane where the cytoskeleton interacts with proteins of the extracellular matrix. Focal adhesion kinase (FAK) is a protein tyrosine kinase which is recruited at an early stage to focal adhesions and which mediates many of the downstream responses. FAK subsequently interacts with a number of down-stream signalling proteins, including the adaptor protein Grb2 and the p85 _-subunit of phosphatidylinositol 3 kinase (PI3 kinase) (Figure 1). biop.ox.ac.uk /www/lj2001/noble/noble_01.html   (671 words)

PTK2 - PTK2 protein tyrosine kinase 2 FAK is a focal adhesion kinase that is phosphorylated on tyrosine in activated platelets. Focal adhesion kinase (FAK) is a non-receptor tyrosine kinase implicated in signalling pathways mediated by integrins and G-protein-coupled receptors (GPCRs). Adhesion of human platelets to collagen under arterial flow conditions mediated by the alpha 2 beta 1 integrin increased tyrosine phosphorylation of several proteins, one of which was the focal adhesion tyrosine kinase, pp125FAK. www.ihop-net.org /UniPub/iHOP/gi/91470.html   (5978 words)

Home : Cell Migration Gateway Normally non-migratory or slow moving cells display focal adhesions, large integrin clusters that are tightly adherent and appear to be dependant on Rho-stimulated myosin contractility. The disassembly of adhesions at the rear of the cell and the retraction of the cell’s tail complete the cycle of migration and enable cell translocation. The release of adhesions at the rear of the cell facilitates protrusive activity at the front of the cell, contributes to the overall polarization and provides positive feedback for the continued cycle of migration. www.cellmigration.org /science   (2120 words)

Interactive Fly, Drosophila Focal adhesion kinase (FAK) was one of the first molecules identified as playing a role in integrin signaling. FAK is the founder member of a structurally conserved family of cytoplasmic nonreceptor protein-tyrosine kinases implicated in controlling cellular responses to the engagement of cell surface receptors. Like FAK, Pyk2 tyrosine phosphorylation can be stimulated by integrin activation, but this is generally a weak response, and stronger Pyk2 activation is elicited by elevation of intracellular Ca2+ levels, particularly in response to activation of G protein-coupled receptors (Palmer, 1999 and references therein). www.sdbonline.org /fly/cytoskel/fak1.htm   (1852 words)

Dr. George Plopper's Research Laboratory, Rensselaer Polytechnic Institute Our general hypothesis is that adhesion to ECM molecules activates a subset of intracellular signaling pathways associated with integrin receptors, and that this signaling controls cell behaviors by modulating the organization of the cytoskeleton.
