UBE2G2 and infection: Interestingly, while synthesis of the structural proteins (E, prM) was only mildly slower in Ube2g2-deficient cells, particularly at 24 h post infection (Fig. 3d, g), synthesis of non-structural proteins was followed by their rapid degradation over time in the rUbe2g2−/− and rUbe2g2C89K cells (Fig. 3e–g).
