WebOct 8, 2004 · Starting from a comparative study of different Ca 2+ chelators on the G-protein-induced inhibition of the Ca V 2.1 Ca channels, we demonstrate that BAPTA and DM-nitrophen are able to interact, in a Ca 2+ - and lipid-dependent manner, with phospholipid monolayers. Critical insertion pressure and sensitivity to charged lipids … WebOct 1, 1998 · DM-Nitrophen and NP-EGTA have structures deriving from EDTA and from EGTA, respectively (Fig. 1), with the addition of groups that influence the affinity of the molecule for Ca 2+. When the photolabile bond is broken, the structural change causes a decrease in the affinity of the chelator for Ca 2+ with consequent release of the ion.
WebIn experiments with resealed human erythrocyte ghosts, irradiation of ghosts containing the DM-nitrophen-Ca2+ complex activates a Ca2+-dependent K+ efflux pathway, which is not observed in the absence of illumination. DM-nitrophen is sufficiently stable and …
WebLarger [Ca 2+] i jumps elicited by photolysis of DM-nitrophen evoke greater I Ca inactivation, but no potentiation, perhaps because of the more transient rise in [Ca 2+] i when DM-nitrophen is photolyzed.
