Contrasting effects of α-synuclein and γ-synuclein on the phenotype of cysteine string protein α (CSPα) null mutant mice suggest distinct function of these proteins in neuronal synapses.
In neuronal synapses, neurotransmitter-loaded vesicles fuse with presynaptic plasma membrane in a complex sequence of tightly regulated events. The assembly of specialized SNARE complexes plays a pivotal role in this process. The function of the chaperone cysteine string protein α (CSPα) is important for synaptic SNARE complex formation, and mice lacking this protein develop severe synaptic dysfunction and neurodegeneration that lead to their death within 3 months after birth. Another presyna...Expand abstract
