      BACKGROUND: . Integrins induce the formation of large complexes of cytoskeletal and signaling proteins, which regulate many intracellular processes. The activation and assembly of signaling complexes involving focal adhesion kinase (FAK) occurs late in integrin signaling, downstream from actin polymerization. Our previous studies indicated that integrin-mediated activation of the non-receptor tyrosine kinase Syk in hematopoietic cells is independent of FAK and actin polymerization, and ...

      Tyrosine phosphorylation of multiple platelet proteins is stimulated by thrombin and other agonists that cause platelet aggregation and secretion. The phosphorylation of a subset of these proteins, including a protein tyrosine kinase, pp125FAK, is dependent on the platelet aggregation that follows fibrinogen binding to integrin alpha IIb beta 3. In this report, we examined whether fibrinogen binding, per se, triggers a process of tyrosine phosphorylation in the absence of exogenous ...

      Agonist stimulation of platelets induces multiple waves of tyrosine phosphorylation, several of which are dependent on the integrin alpha IIb beta 3. At least two classes of protein tyrosine kinases are activated during various stages of platelet activation, 1) Src family tyrosine kinases are activated during an early phase of platelet activation by an integrin-independent mechanism and 2) pp125FAK is activated during a late stage of platelet activation, and it is dependent on platelet ...

      Integrins regulate cell adhesion and motility through tyrosine kinases, but initiation of this process is poorly understood. We find here that Src associates constitutively with integrin alphaIIbbeta3 in platelets. Platelet adhesion to fibrinogen caused a rapid increase in alphaIIbbeta3-associated Src activity, and active Src localized to filopodia and cell edges. Csk, which negatively regulates Src by phosphorylating Tyr-529, was also constitutively associated with alphaIIbbeta3. ...

      FAK is a focal adhesion kinase that is phosphorylated on tyrosine in activated platelets. Induction of FAK phosphorylation requires both fibrinogen binding to integrin alpha IIb beta 3 and post-occupancy events during agonist-induced platelet aggregation or platelet spreading on a fibrinogen matrix. To identify the signaling pathways necessary for tyrosine phosphorylation of FAK, we have examined the conditions that stimulate or inhibit this phosphorylation in platelets in which ...

      pp125FAK (focal adhesion kinase) a protein tyrosine kinase that may mediate cellular responses to adhesion, is activated and tyrosine-phosphorylated when platelets adhere to fibrinogen via the integrin, alpha IIb beta 3. To determine whether either of the cytoplasmic tails of alpha IIb beta 3 regulates FAK phosphorylation, CHO cells were stably transfected with alpha IIb beta 3 or various cytoplasmic tail truncation mutants. Cells expressing wild-type alpha IIb beta 3 or alpha IIb beta 3 ...

      Specific cleavage of the transmembrane molecule, CUB domain-containing protein-1 (CDCP1), by plasmin-like serine proteases induces outside–in signal transduction that facilitates early stages of spontaneous metastasis leading to tumor cell intravasation, namely cell escape from the primary tumor, stromal invasion and transendothelial migration. We identified active β1 integrin as a biochemical and functional partner of the membrane-retained 70-kDa CDCP1 fragment, newly generated from its ...

      Platelet activation is accompanied by the appearance on the platelet surface of approximately 45,000 receptor sites for fibrinogen. The binding of fibrinogen to these receptors is required for platelet aggregation. Although it is established that the fibrinogen receptor is localized to a heterodimer complex of the membrane glycoproteins, IIb and IIIa, little is known about the changes in this complex during platelet activation that result in the expression of the receptor. In the present ...

      Mice deficient in the adaptor Src homology 2 domain-containing leukocyte phosphoprotein of 76 kD (SLP-76) exhibit a bleeding disorder and lack T cells. Linker for activation of T cells (LAT)-deficient mice exhibit a similar T cell phenotype, but show no signs of hemorrhage. Both SLP-76 and LAT are important for optimal platelet activation downstream of the collagen receptor, GPVI. In addition, SLP-76 is involved in signaling mediated by integrin alphaIIbbeta3. Because SLP-76 and LAT ...

      pp72syk is essential for development and function of several hematopoietic cells, and it becomes activated through tandem SH2 interaction with ITAM motifs in immune response receptors. Since Syk is also activated through integrins, which do not contain ITAMs, a CHO cell model system was used to study Syk activation by the platelet integrin, alpha IIb beta 3. As in platelets, Syk underwent tyrosine phosphorylation and activation during CHO cell adhesion to alpha IIb beta 3 ligands, ...

      Activation of human platelets by complement proteins C5b-9 is accompanied by the release of small plasma membrane vesicles (microparticles) that are highly enriched in binding sites for coagulation factor Va and exhibit prothrombinase activity. We have now examined whether assembly of the prothrombinase enzyme complex (factors VaXa) is directly linked to the process of microparticle formation. Gel-filtered platelets were incubated without stirring with various agonists at 37 degrees C, ...

      To analyze the basis of affinity modulation of integrin function, we studied cloned stable Chinese hamster ovary cell lines expressing recombinant integrins of the beta 3 family (alpha IIb beta 3 and alpha v beta 3). Antigenic and peptide recognition specificities of the recombinant receptors resembled those of the native receptors found in platelets or endothelial cells. The alpha IIb beta 3-expressing cell line (A5) bound RGD peptides and immobilized fibrinogen (Fg) but not soluble ...

      Cholesterol-rich membranes are the hallmark of "spur" red cells. Spur cells accumulate cholesterol from cholesterol-rich serum lipoproteins. Previous studies suggested that this added cholesterol is responsible for both the altered morphology and the destruction of spur cells. To examine this process in the absence of other serum factors, cholesterol-lecithin dispersions with varying amounts of unesterified cholesterol (C) relative to phospholipid (P) were prepared, and their influence ...

      The platelet membrane glycoprotein IIb-IIIa complex (GPIIb-IIIa) recognizes peptides containing the amino acid sequence Arg-Gly-Asp, a sequence present at two locations in the alpha chain of fibrinogen. GPIIb-IIIa also interacts with peptides containing the carboxyl-terminal 10-15 residues of the fibrinogen gamma chain. We found that the alpha chain tetrapeptide, Arg-Gly-Asp-Ser (RGDS), and the gamma chain peptide, Leu-Gly-Gly-Ala-Lys-Gln-Ala-Gly-Asp-Val (LGGAKQAG-DV), each inhibited ...
