Functional Role of Serine Residues of Transmembrane Dopamin VII in Signal Transduction of CB2 Cannabinoid Receptor
Man-Hee Rhee 대한수의학회 Journal of Veterinary Science 7 Pages
대한수의학회 Journal of Veterinary Science 2002, 제 3권 제 3호 7 185-191 (7 pages)
Using site-directed mutagenesis technique, I have replaced serine 285 and serine 292 with the alanine, and assessed the binding of agonist and signaling such as the inhibition of adenylyl cyclase activity. I have found that serine 292 has an important role in the signal transduction of cannabinoid agonists, HU-210 and CP55940, but not in that of aminoalkylindoles derivatives WIN55,212-2. All mutants express well in protein level determined by western blot using monoclonal antibody HA 11 as... -

Angiogenesis plays an essential role in embryo development, tissue repair, inflammatory diseases, and tumor growth. In the present study, we showed that endothelial nitric oxide synthase (eNOS) regulates retinal angiogenesis. Mice that lack eNOS showed growth retardation, and retinal vessel development was significantly delayed. In addition, the number of tip cells and filopodia length were significantly reduced in mice lacking eNOS. Retinal endothelial cell proliferation was significantly... -
The Critical Roles of Zinc: Beyond Impact on Myocardial Signaling

Zinc has been considered as a vital constituent of proteins, including enzymes. Mobile reactive zinc (Zn2+) is the key form of zinc involved in signal transductions, which are mainly driven by its binding to proteins or the release of zinc from proteins, possibly via a redox switch. There has been growing evidence of zinc’s critical role in cell signaling, due to its flexible coordination geometry and rapid shifts in protein conformation to perform biological reactions. The importance and... -
G Protein-Coupled Receptor Signaling in Gastrointestinal Smooth Muscle

Contraction of smooth muscle is initiated by an increase in cytosolic Ca2 leading to activation of Ca2/ calmodulin-dependnet myosin light chain (MLC) kinase and phosphorylation of MLC. The types of contraction and signaling mechanisms mediating contraction differ depending on the region. The involvement of these different mechanisms varies depending on the source of Ca2 and the kinetic of Ca2 mobilization. Ca2 mobilizing agonists stimulate different...
