Alteration by v-Ki-ras in NaF, cholera toxin and forskolin-induced adenylate cyclase activation in NIH/3T3 fibroblast cells.

Abstract:

:It has been suggested that ras proteins are involved in the transmembrane signaling mechanism and they share structural features with GTP-binding proteins. To identify the role of ras oncogene and it's products in the coupling mechanisms of GTP-binding proteins to adenylate cyclase, we examined effect of NaF, cholera toxin and forskolin in normal and v-Ki-ras transformed NIH/3T3 fibroblast cells. In transformants, adenylate cyclase activity was markedly enhanced by NaF and cholera toxin, in contrast to normal cells. It is suggested that ras oncogene proteins plays enhancing role in coupling of GTP-binding proteins to adenylate cyclase.

  • Phosphorylation of VASP by AMPK alters actin binding and occurs at a novel site.

    abstract::Vasodilator-stimulated phosphoprotein (VASP) is an actin regulatory protein that functions in adhesion and migration. In epithelial cells, VASP participates in cell-cell adhesion. At the molecular level, VASP drives actin bundling and polymerization. VASP activity is primarily regulated by phosphorylation. Three physi...
