Distinct protein kinases regulate SNAP-25 expression in chromaffin cells
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 2003-02-01)
The contribution of distinct Ca2+-sensitive protein kinases to the regulation of the expression of the synaptosomal-associated protein SNAP-25 was examined in bovine chromaffin cells. Prolonged incubation with high K+ (38 ...
Wnt5a inhibits K+ currents in hippocampal synapses through nitric oxide production

Tyrosine 251 at the C-terminus of Neuronal Glycoprotein M6a is Critical for Neurite Outgrowth
(Wiley-liss, Div John Wiley & Sons Inc, 2015-09)
Neuronal glycoprotein M6a is involved in neuronal plasticity, promoting neurite and filopodia outgrowth and, likely, synaptogenesis. Polymorphisms in the human M6a gene GPM6A have recently been associated with mental ...
Protein tyrosine kinase inhibitors modify kainic acid-induced epileptiform activity and mossy fiber sprouting but do not protect against limbic cell death
(Associação Brasileira de Divulgação Científica, 2008-05-01)
Intrahippocampal administration of kainic acid (KA) induces synaptic release of neurotrophins, mainly brain-derived neurotrophic factor, which contributes to the acute neuronal excitation produced by the toxin. Two protein ...
Trypanosoma cruzi 175-kDa protein tyrosine phosphorylation is associated with host cell invasion
(Academic Press Inc, 1998-06-01)
We examined the requirement of Trypanosoma cruzi protein tyrosine phosphorylation for parasite entry into mammalian cells and analyzed the profile of phosphorylated proteins in infective trypomastigotes. Treatment of ...
Evidence for the involvement of Proline-rich Tyrosine Kinase 2 (PYK2) in tyrosine phosphorylation downstream of PKA activation during human sperm capacitation
(Oxford University Press, 2014-09-01)
Sperm capacitation involves an increase in intracellular Ca(2+) concentration as well as in protein kinase A (PKA)-dependent protein tyrosine (Tyr) phosphorylation. Interestingly, in humans, a decrease in extracellular ...
