Mitochondrial transcription factor A (TFAM) regulates mitochondrial biogenesis, which is downregulated by extracellular signal-regulated protein kinases (ERK1/2) in cells treated chronically with the complex I inhibitor 1-methyl-4-phenylpyridinium (MPP+). We utilized mass spectrometry to identify ERK1/2-dependent TFAM phosphorylation sites. Mutation of TFAM at serine 177 to mimic phosphorylation recapitulated the effects of MPP+ in decreasing the binding of TFAM to the light strand promoter, suppressing mitochondrial transcription. Mutant TFAM was unable to affect respiratory function or rescue the effects of MPP+ on respiratory complexes. These data disclose a novel mechanism by which ERK1/2 regulates mitochondrial function through direct phosphorylation of TFAM.
