In vitro and in vivo specificity of ubiquitination and degradation of STAT1 and STAT2 by the V proteins of the paramyxoviruses simian virus 5 and human parainfluenza virus type 2

Abstract excerpt

Previous work has documented that the V protein of simian virus 5 (SV5) targets STAT1 for proteasome-mediated degradation, whilst the V protein of human parainfluenza virus type 2 (hPIV2) targets STAT2. Here, it was shown that the processes of ubiquitination and degradation could be reconstructed in vitro by using programmed rabbit reticulocyte lysates. Using this system, the addition of bacterially expressed and...
