In this paper, we report an unexpected, acute effect of GDNF on Atype potassium channels, leading to a potentiation of neuronal excitability, in the dopaminergic neurons in culture as well as in adult brain slices. Further, we show that GDNF regulates the K+ channels through a mechanism that involves activation of MAP kinase. Thus, this study has revealed, for the first time, an acute modulation of ion channels by GDNF. Our findings challenge the classic view of GDNF as a longterm survival factor for midbrain dopaminergic neurons, and suggest that the normal function of GDNF is to regulate neuronal excitability, and consequently dopamine release. These results may also have implications in the treatment of Parkinson’s disease.Due to a direct petition and conflict of interest, we request that Drs. XXX of Harvard Univ., and YY of Yale Univ. not be considered as reviewers. With thanks for your consideration, I amSincerely yours,case2Dear Editor,We would like to submit the enclosed manuscript entitled Ca2+binding protein frequenin mediates GDNFinduced potentiation of Ca2+ channels and transmitter release, which we wish to be considered for publication in Neuron.We believe that two aspects of this manuscript will make it interesting to general readers of Neuron. First, we report that GDNF has a longterm regulatory effect on neurotransmitter release at the neuromuscular synapses. This provides the first physiological evidence for a role of this new family of neurotrophic factors in functional synaptic transmission. Second, we show that the GDNF effect is mediated by enhancing the expression of the Ca2+binding protein frequenin. Further, GDNF and frequenin facilitate syna
