Cytochrome c (Cyt c ) is a multifunctional protein that operates as an electron carrier in the mitochondrial electron transport chain and plays a key role in apoptosis. We have previously shown that tissue‐specific phosphorylations of Cyt c in the heart, liver, and kidney play an important role in the regulation of cellular respiration and cell death. Here, we report that Cyt c purified from mammalian brain is phosphorylated on S47 and that this phosphorylation is lost during ischemia. We have characterized the functional effects in vitro using phosphorylated Cyt c purified from pig brain tissue and a recombinant phosphomimetic mutant (S47E). We crystallized S47E phosphomimetic Cyt c at 1.55 Å and suggest that it spatially matches S47‐phosphorylated Cyt c , making it a good model system. Both S47‐phosphorylated and phosphomimetic Cyt c showed a lower oxygen consumption rate in reaction with isolated Cyt c oxidase, which we propose maintains intermediate mitochondrial membrane potentials under physiologic conditions, thus minimizing production of reactive oxygen species. S47‐phosphorylated and phosphomimetic Cyt c showed lower caspase‐3 activity. Furthermore, phosphomimetic Cyt c had decreased cardiolipin peroxidase activity and is more stable in the presence of H 2 O 2 . Our data suggest that S47 phosphorylation of Cyt c is tissue protective and promotes cell survival in the brain.—Kalpage, H. A., Vaishnav, A., Liu, J., Varughese, A., Wan, J., Turner, A.
