NEUROBIOLOGY How Not to Differentiate a Neuron
What do neuronal precursor cells and non-neuronal cells have in common? Neither expresses the genes typical of differentiated neurons. Yeo et al. now show what else is in common: expression of certain SCP phosphatases. The SCP phosphatases serve to repress the expression of neuronal genes, perhaps stabilizing non-neuronal differentiation programs or keeping progenitor cells in check as they wait for their call to action. Inhibition of the SCP phosphatase activity increased neuronal differentiation. It appears that SCP phosphatase activity acts globally to silence neuronal genes in neuronal precursors and non-neuronal cells.
