Paxillin, a tyrosine phosphorylated focal adhesion-associated protein binds to the carboxyl terminal domain of focal adhesion kinase.
Focal adhesion kinase (pp125FAK or FAK) and paxillin colocalize with integrins in structures called focal adhesions. pp125FAK plays an important role in the transmission of integrin-induced cytoplasmic signals. Paxillin has also been implicated in cell signaling by virtue of its association with the protein tyrosine kinases pp60src and Csk (C-terminal Src kinase) as well as with the adapter/onc...
متن کاملDown regulation of GTPase regulator associated with the focal adhesion kinase (GRAF) gene expression in patients with acute myeloblastic leukemia
Introduction: GTPase regulator associated with focal adhesion kinase (GRAF) is a recently identified GTPase activating protein that has the tumor suppressor properties. However, the expression level of GRAF in leukemia had received less attention. The main purpose of this research was the evaluating of the expression level of GRAF in patients with acute myeloid leukemia (AML). Materials and met...
متن کاملSteel factor enhances integrin-mediated tyrosine phosphorylation of focal adhesion kinase (pp125FAK) and paxillin.
Integrin-mediated interaction of hematopoietic progenitor cells with bone marrow stromal extracellular matrix components is important in hematopoiesis. Focal adhesion kinase (pp125FAK) plays a central role in signal transduction through integrin receptors. We studied matrix-integrin interaction and subsequent signaling in human growth factor-dependent cell line, TF-1. Adherence of unstimulated ...
متن کاملFocal adhesion kinase (pp125FAK) cleavage and regulation by calpain.
Focal adhesion kinase (125 kDa form; pp125FAK) is a widely expressed non-receptor tyrosine kinase that is implicated in integrin-mediated signal transduction. We have identified a novel means of pp 125FAK regulation in human platelets, in which this kinase undergoes sequential proteolytic modification from the native 125 kDa form to 90, 45 and 40 kDa fragments in thrombin-, collagen- and ionoph...
متن کاملWeak expression of focal adhesion kinase (pp125FAK) in patients with cervical cancer is associated with poor disease outcome.
PURPOSE The pp125 focal adhesion kinase (FAK) plays a pivotal role in tumor cell signaling. FAK expression has been linked to tumor cell invasion and metastasis, but data on cervical cancer are inconclusive. Our goal was to investigate FAK expression in cervical cancer and to assess whether its expression correlates with prognosis. EXPERIMENTAL DESIGN FAK expression was examined using immunoh...
