REVIEW Synaptic Cysteine Sulfhydryl Groups as Targets of Electrophilic Neurotoxicants
Many structurally diverse chemicals (e.g., acrylamide, 2,4dithiobiuret, methylmercury) are electrophiles and cause synaptic dysfunction by unknown mechanisms. The purpose of this Forum review is to discuss the possibility that highly nucleophilic cysteine thiolate groups within catalytic triads of synaptic proteins represent specific and necessary targets for electrophilic neurotoxicants. Most ...

متن کاملIntracellular signal transduction pathways as targets for neurotoxicants.
The multiple cascades of signal transduction pathways that lead from receptors on the cell membrane to the nucleus, thus translating extracellular signals into changes in gene expression, may represent important targets for neurotoxic compounds. Among the biochemical steps and pathways that have been investigated are the metabolism of cyclic nucleotides, the formation of nitric oxide, the metab...
متن کاملQuercetin Targets Cysteine String Protein (CSPα) and Impairs Synaptic Transmission
BACKGROUND Cysteine string protein (CSPalpha) is a synaptic vesicle protein that displays unique anti-neurodegenerative properties. CSPalpha is a member of the conserved J protein family, also called the Hsp40 (heat shock protein of 40 kDa) protein family, whose importance in protein folding has been recognized for many years. Deletion of the CSPalpha in mice results in knockout mice that are n...
متن کاملSulfhydryl Groups in Proteins
Egg albumin in the native, unaltered state, does not give tests characteristic of sulfhydryl groups. When, however, this protein is treated in any one of several ways, such as by heat (8, 9, 17), ultraviolet irradiation (lo), shaking (lo), or by solution in urea or other amides (7), free sulfhydryl groups make their appearance. The amount of free -SH groups appearing in egg albumin through the ...
