PRMT3 (protein arginine methyltransferase 3) is one of four type I arginine methyltransferases that catalyse the formation of asymmetric dimethylarginine. PRMT3 is unique in that its N-terminus harbours a C2H2 zinc-finger domain that is proposed to confer substrate specificity. In addition, PRMT3 is the only type I enzyme that is restricted to the(More)
Tumor cells rely on high concentrations of amino acids to support their growth and proliferation. Although increased macropinocytic uptake and lysosomal degradation of the most abundant serum protein, albumin, in Ras-transformed cells can meet these demands, it is not understood how the majority of tumor cells that express wild type Ras achieve this. In the(More)
Tissue-specific iron content is tightly regulated to simultaneously satisfy specialized metabolic needs and avoid cytotoxicity. In the brain, disruption of iron homeostasis may occur in acute as well as progressive injuries associated with neuronal dysfunction and death. We hypothesized that adverse effects of disrupted metal homeostasis on brain function(More)
