title: Effect of the S-100 protein on the RNA-polymerase activity in brain nucleoli isolated from newborn rat.
abstract: The structural integrity of the nucleus is not a prerequisite for the action of the S-100 protein on the RNA-polymerase activity in brain nuclei. In fact the protein also stimulates the enzyme activity in sonicated nuclei of newborn rat, as well as directly in isolated nucleoli from the same source.
