The minimum structure of the Raf-1 serine/threonine kinase that recognizes active Ras was used to create a green fluorescent fusion protein (GFP) for monitoring Ras activation in live cells. In spite of its ability to bind activated Ras in vitro, the Ras binding domain (RBD) of Raf-1 (Raf-1[51-131]GFP) failed to detect Ras in Ras-transformed NIH 3T3(More)
Impairment in endothelial cell (EC) function plays a central role in vascular diseases (e.g. atherosclerosis, restenosis, diabetic angiopathies, microvascular angina, peripheral arterial disease). BRX-235 (a novel small molecule synthesized by Biorex, Hungary) has a potent vasculoprotective activity in different in vivo and in vitro studies. Since the(More)
Cytosolic Ca2+ ([Ca2+]c) signals triggered by many agonists are established through the inositol 1,4,5-trisphosphate (IP3) messenger pathway. This pathway is believed to use Ca2+-dependent local interactions among IP3 receptors (IP3R) and other Ca2+ channels leading to coordinated Ca2+ release from the endoplasmic reticulum throughout the cell and coupling(More)
Virtually all functions of a cell are influenced by cytoplasmic [Ca(2+)] increases. Inositol 1,4,5-trisphosphate receptor (IP(3)R) channels, located in the endoplasmic reticulum (ER), release Ca(2+) in response to binding of the second messenger, IP(3).IP(3)Rs thus are part of the information chain interpreting external signals and transforming them into(More)
