Evolutionarily conserved developmental pathways


Lateral inhibition - The Notchpathway

The Notch pathway functions in neurogenesis and other developmentalpathways to assure that cell fate is restricted to a limited number ofprogenitors. Notch and Wingless pathways talk to each other through Dishevelled, which is an integral part of the Wingless pathway and physically interactions with the Notch carboxylterminus.
