Rfwd2 is an E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of target proteins.
E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates.
It is involved in JUN ubiquitination and degradation and directly involved in p53 (TP53) ubiquitination and degradation, thereby abolishing p53-dependent transcription and apoptosis.
Ubiquitinates p53 independently of MDM2 or RCHY1.
Rfwd2 probably mediates E3 ubiquitin ligase activity by functioning as the essential RING domain subunit of larger E3 complexes.
In contrast, it does not constitute the catalytic RING subunit in the DCX DET1-COP1 complex that negatively regulates JUN, the ubiquitin ligase activity being mediated by RBX1.
