Enhancement of synaptic vesicle attachment to the plasma membrane fraction by copper.

W Hoss, M Formaniak.   

Abstract

Synaptic vesicles from rat brain were labeled with 125I, and the association of the vesicles with other subcellular components of brain was examined using a centrifugation assay. Copper at micromolar concentrations enhances the binding of the vesicles to the synaptic membrane as well as other fractions. Magnesium, Ca2+, and calmodulin with Ca2+ are ineffective. There is virtually no binding of synaptic vesicles to the microtuble fraction and only a slight enhancement with Cu2+. These findings support the hypothesis that Cu may serve as a bridge between synaptic vesicles and the plasma membrane.
