Research Abstract |
We investigated the metabolic pathways of asymmetric dimethylarginine (ADMA) in blood cells to elucidate the regulatory mechanism of elevation of plasma ADMA, a novel risk factor of cardiovascular diseases. We found for the first time that ADMA was actively metabolized by PRMT1 and DDAH1 in erythrocytes and identified catalase that contains ADMA residue and interacts with PRMT1. These findings suggest that catalase is a potential target for methylation by PRMT1 in erythrocytes and may be a source of plasma ADMA.
