Smurf

Gene

Smurf

Protein

E3 ubiquitin-protein ligase Smurf1

Organism

Drosophila melanogaster

Length

1061 amino acids

Function

E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Down-regulates Dpp signaling after gastrulation by promoting MAD ubiquitination and subsequent degradation.
