The role of the Ras signalling molecule, C3G, in the interaction of neural precursor cells and their environment

Funded Activity Summary

Developmental brain disorders affect 1-3% of the population. The mental retardation disease spectrum includes neuronal migration disorders and neural precursor proliferation disorders. We propose to study a molecular mechanism regulating neuronal migration, survival and proliferation. We have identified a protein, C3G, which is essential for three aspects of nervous system development: (A) C3G limits neural precursor cell proliferation. (B) C3G is essential for neuronal survival. (C) C3G is crucial for neuronal migration. C3G acts in a cascade of proteins, known as the Ras signalling pathway, which transmits signals from the extracellular environment into the cell nucleus to elicit appropriate responses of the cell to cues from the outside. We will identify proteins that, together with C3G, affect the important processes of neural precursor proliferation, and neuron survival and migration. This project will fully characterise a key regulatory mechanism of cellular processes crucial to the development of normal intelligence.
