Defining a role for the STONED proteins in the synaptic vesicle cycle

Funded Activity Summary

Nerve cells communicate with each other by means of chemical neurotransmitters. The level of communication is strictly controlled, and changes in the level, either up or down, is known as synaptic plasticity. This plasticity is thought to underly changes in the brain that account for both long and short term memory. Uncontrolled alterations in plasticity can also induce abnormal brain function, resulting in neurological disorders. Changes in the release of neurotransmitter are regulated at the molecular level by unknown mechanisms, however the chemical neurotransmitters are enclosed in small vesicles and it is believed that the control of the release of these vesicles, and their recycling, are important components of this mechanism. We have identified a gene that encodes two novel proteins of neurotransmission. Mutations that alter these genes can result in either increased or decreased synaptic activity. By using a combination of genetic and molecular techniques we propose to investigate how one of these two proteins operate to alter synaptic activity, as well as attempting to show how it interacts with other components of the synaptic machinery.
