CA2 — SNAP25

Text-mined interactions from Literome

García-Palomero et al., J Neurochem 2000 : These findings, together with the fact that nicotinic receptor activation or Ca2+ release from internal stores also enhanced SNAP-25 protein expression, suggest that an increment of cytosolic Ca2+ concentration ([Ca2+]), rather than its source or Ca2+ entry pathway, is the critical signal to induce the protein expression
Nakata et al., Cell Struct Funct 1999 (Diabetes Mellitus, Type 1...) : SNAP at 200 microM increased cytosolic Ca2+ concentration ([Ca2+]i) and induced apoptosis
Chieregatti et al., Traffic 2002 : These results show that Ca2+ modulates dynamic docking of granules to the plasma membrane and that this process is due to a Ca2+ dependent interaction between SNAP-25 and Synaptotagmin 1
Zhang et al., Neuron 2002 (Calcium Signaling...) : Synaptotagmin is a proposed Ca2+ sensor on the vesicle for regulated exocytosis and exhibits Ca2+ dependent binding to phospholipids, syntaxin, and SNAP-25 in vitro, but the mechanism by which Ca2+ triggers membrane fusion is uncertain ... Previous studies suggested that SNAP-25 plays a role in the Ca2+ regulation of secretion ... These results indicate that the Ca2+ dependent interaction of synaptotagmin with SNAP-25 is essential for the Ca2+ dependent triggering of membrane fusion
Chen et al., J Mol Biol 2005 : Indeed, overexpression of SNAP-25 bearing mutations in two putative Ca2+ ligands ( E170A/Q177A ) causes a decrease in the Ca2+-cooperativity of exocytosis in chromaffin cells
Ando et al., J Neurochem 2005 : Calpain inhibitors abolished the Ca2+ dependent cleavage of SNAP-25 and markedly facilitated Ca2+ dependent glutamate ( Glu ) release from cerebellar granule cells
Shen et al., Brain Res 2006 (Calcium Signaling) : S-nitroso-N-acetylpenicillamine (SNAP) , a NO donor, enhanced the ATP induced increase of the intracellular Ca2+ concentrations ([Ca2+]i) , while L-NAME inhibited it
Lopez et al., FASEB J 2007 : Previous studies indicate that the process requires Rab3 dependent tethering of membranes, SNARE complex assembly, and Ca2+ mediated activation of synaptotagmin
Lermioglu et al., Biochem J 1991 : Increasing cell density was significantly correlated with the decrease in cytosolic free Ca2+ induced by ANP ( 99-126 ) or SNAP
Ramakrishnan et al., J Biol Chem 2009 (Deafness) : The native otoferlin C2F domain bound syntaxin 1A and SNAP-25 in a Ca2+ dependent manner ( with optimal 61 microm free Ca2+ required for binding )
Sokolovski et al., Mol Plant 2008 (Ion Channel Gating) : Here, we report one mode of action for the SNARE mediated directly through alterations in Ca2+ channel gating and its consequent effects on cytosolic-free [ Ca2+ ] ( [ Ca2+ ] i ) elevation
Kannan et al., Am J Physiol 1997 : SNAP inhibited ACh induced SR Ca2+ release at both 0 and 2.5 mM extracellular Ca2+ ... Degraded SNAP had no effect on ACh induced SR Ca2+ release ... SNAP also inhibited caffeine induced SR Ca2+ release ... These results suggest that, in porcine TSM cells, SNAP reduces the intracellular Ca2+ response to ACh and caffeine by inhibiting SR Ca2+ release through both IP3 and RyR, but not by inhibiting influx or repletion of the SR Ca2+ stores
