All life forms depend on proteins which are encoded by genes. Whereas the regulation of protein amounts and activities is analysed in many laboratories, the signals that lead to a regulated degradation of specific proteins are far less well understood. A German team led by the Freiburg-based biologist Professor Ralf Reski has discovered substrates and interaction partners of the so-called N-end rule pathway of protein degradation in the moss Physcomitrella patens. The study is published in the journal “Molecular and Cellular Proteomics”.
