WWP2 (mouse Wwp2) is an E3 ubiquitin ligase that specifically interacts with the POU transcription factor Oct-4 via its WW domain and promotes Oct-4 ubiquitination both in vivo and in vitro; a catalytically inactive point mutant abolishes this ubiquitination; overexpression of WWP2 in embryonic stem cells reduces Oct-4 transcriptional activity, and fusion of a single ubiquitin to Oct-4 inactivates its transcriptional activity. |
