CLPX regulates the terminal steps of heme synthesis.A, ALAS2 activity was significantly increased in Clpx^−/− and Clpp^−/− cells. B, Clpx^−/− and Clpp^−/− cells produced significantly more ALA than WT cells. C, Clpx^−/− and Clpp^−/− cells produced significantly more PPIX than WT cells. D, PPOX protein levels were decreased in undifferentiated Clpx^−/− and Clpp^−/− cells but not appreciably in differentiated cells. However, FECH protein levels were decreased, N = 3. E, PPOX activity was decreased in Clpx^−/− cells but was unaltered in Clpp^−/− cells. F, FECH activity was decreased in undifferentiated Clpx^−/− cells, relative to wild-type cells. The FECH activity of Clpp^−/− cells was unaltered. In differentiating MEL cells, FECH activity was decreased in both Clpx^−/− and Clpp^−/− cells. ∗p < 0.05. Error bars indicate SD.
