E3 ubiquitin-protein ligase MARCHF6 (MARCHF6)

E3 ubiquitin-protein ligase that promotes ubiquitination of DIO2, leading to its degradation. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfer the ubiquitin to targeted substrates.
