- "Several independent experiments showed that UV-induced ubiquitylation was reproducibly affected only by Nedd4 siRNA (Figure 5C, compare lane 4 with lane 14 [control] and other knockdowns; data not shown). This indicates that Nedd4 is required for UV-induced ubiquitylation of RNAPII in vivo." PMID:17996703
- "To investigate whether they could support human RNAPII ubiquitylation in vitro, highly purified human RNAPII was used as substrate, with human Uba1 and UbcH7 (or UbcH5C) involved as E1 and E2, respectively (Figure 6C, lanes 7–10). In this highly purified, reconstituted human RNAPII ubiquitylation system (see Figure S4 for purity of these proteins), Nedd4 (and Smurf1), but none of the other Rsp5 homologs, supported robust ubiquitylation of RNAPII (Figure 6C, lanes 2 and 3)."
