MST3 Proteins and Enzymes

The growth of axons is fundamental to the development and repair of brain circuitry. It has been shown that Mst3, a neuron-specific homolog of the yeast kinase Ste20, is critical for axon outgrowth. Mst3 is activated in response to trophic factors, and suppressing its expression or its function blocks axon outgrowth (1). Mst3 has been recently demonstrated to undergo a caspase-mediated cleavage during apoptosis. The proteolytic cleavage of the C-terminus of Mst3 caused nuclear translocation of ...
