... promoted cancer cell migration in vitro and metastasis in vivo . The latest research from Sabine’s team has demonstrated that in H1299 lung cancer cells, the mechanism by which ITPKA promoted migration and invasion was predominantly depending on the ability of binding to F-actin, which will induce cancer...

...-regulation is associated with bad prognosis and it has been shown that a high level of ITPKA increases migration and invasion of lung cancer cell lines. However, since ITPKA exhibits actin bundling and Ins(1,4,5)P 3 -kinase activity, it was not clear which of these activities account for ITPKA-promoted...

... to maintaining cell homeostasis. Actin, a major constituent of the cytoskeleton, forms many different structures which are acutely sensitive to the cell environment. Furthermore, actin structures interact with and are critically important for the function and regulation of multiple factors involved with mRNA...

... forms of AKT are present in melanoma cells nuclei. Using mass spectrometry in combination with protein-crosslinking and co-immunoprecipitation, we identified a series of putative protein partners of nuclear AKT, including heterogeneous nuclear ribonucleoprotein (hnRNP), cytoskeleton proteins β-actin, γ...

... actin endosome myosins molecular motors Mammals have three class V myosin genes, encoding Myo5a, Myo5b and Myo5c [ 1 ]. Myo5b plays a critical role in the recycling of endosomes to the plasma membrane, and this process is mediated by two Myo5b-binding proteins, i.e. Rab11a and the Rab11...

...Daisy N. Riquelme; Aaron S. Meyer; Melanie Barzik; Amy Keating; Frank B. Gertler The members of the actin regulatory family of Ena/VASP proteins form stable tetramers. The vertebrate members of the Ena/VASP family, VASP, Mena and EVL, have many overlapping properties and expression patterns...

...-derived ECM involves actin cytoskeletal pathways or TSP oligomer state. From tests of a suite of pharmacological inhibitors of small GTPases, actomyosin-based contractility, or actin microfilament integrity and dynamics, cytochalasin D and jasplakinolide treatment of cells were identified to result...

...Katarina Tejle; Karl-Eric Magnusson; Birgitta Rasmusson Phagocytosis by neutrophils, macrophages, and other professional phagocytes requires rapid remodeling of actin. Early phagosomes are surrounded by a rim of F-actin that is disassembled during phagosomoal maturation. Breakdown of periphagosomal...

... are assessment of aggregation and adhesion, secretion, arachidonate metabolism, coagulant activities and the characterization of surface membrane glycoproteins (Day and Rao, 1986). Here we measure alterations of the G-/F-actin equilibrium of platelets. High F-actin values of unstimulated platelets indicate...

...Michael R. Payne; Suzanne E. Rudnick Tropomyosin polymerization is inhibited by DNAse I, an endonuclease which also interacts with G-actin. A 1:4 molar ratio of DNAse I to adult chicken pectoralis muscle tropomyosin almost completely prevents the increased viscosity of tropomyosin under...

...C. Méjean; M. Boyer; J. P. Labbé; J. Derancourt; Y. Benyamin; C. Roustan The interaction of two different anti-actin antibody populations with the myosin subfragment 1-F-actin rigor complex has been studied. In contrast with the 1–7 sequence, the 18–28 sequence appears to be strongly implicated...
