Ca2+/calmodulin-dependent cyclic nucleotide phosphodiesterase in cGMP metabolism in rabbit parotid acinar cells
Ca2+/calmodulin-dependent cyclic nucleotide phosphodiesterase cGMP metabolism rabbit parotid acinar cells
2009/3/2
Muscarinic cholinergic receptor activation provokes cGMP formation in parotid acinar cells. We investigated the involvement of Ca2+/calmodulin-dependent cyclic nucleotide phosphodiesterase (PDE1) in...
In vitro interactions of calmodulin with the ovine proacrosin-acrosin system
acrosome spermatozoa proteolytic activity
2009/1/5
The authors studied the interaction of calmodulin (CaM) with proacrosin and acrosin from ram spermatozoa. CaM binding evaluated by the [125I]-CaM overlay procedure was shown to occur preferentially ...
Implication of Calmodulin-Dependent Phosphodiesterase Type 1 During Bovine Sperm Capacitation
Vinpocetine rolipram cyclic AMP in vitro fertilization motility
2008/12/18
Phosphodiesterases (PDEs) are enzymes that degrade cyclic nucleotides. The calcium-calmodulin dependent PDE type 1 (PDE 1) and the cyclic adenosine monophosphate (cAMP)-specific PDE type 4 (PDE 4) h...
Role of protein kinase C and calmodulin in histamine release in experimental filariasis
Brugia malayi calmodulin histamine lung mast cells Mastomys natalensis peritoneal mast cells protein kinase C
2010/11/29
The allergenic activity of 60 kDa antigen of Brugia malayi adult worm, due to its ability to release histamine from mast cells, has been previously reported by us. To determine the roles of protein ki...
