| Research Abstract |
alpha-Synuclein(a-syn) is the major pathological component of synucleinopathies including Parkinson's disease.In primary mouse hippocampal neuronal cultures, a-syn-positive synapses were colocalized with the excitatory synapse marker vesicular glutamate transporter-1.
When a-syn was evaluated with non-denaturing gels or size exclusion chromatography (SEC) columns, a-syn monomers migrated as 50- to 60-kDa proteins; however, in denaturing gels, they migrated as 15-kDa proteins. The disulfide-linked dimer and oligomer migrated slower than either the unfolded recombinant a-syn or the native a-syn in SEC.As a result,a-Syn exists predominantly as a disordered monomer in CSF.
