In this study, the expression profiles of transcripts linked to ubiquitination (i.e., AREL1, RBBP6, UBA7, UBE2A, UBE2D1, UBE2H, UBE2B, UBE2K, UBE3A) and proteasomal degradation were up-regulated in cells infected with the VSV mutant when compared to mock infection (Figure 8A,B). Here, UBE3A is linked to infection.
