Mouse E3 Ubiquitin-protein Ligase Smurf1, SMURF1 ELI

E3 ubiquitin-protein ligase that acts as a negative regulator of BMP signaling pathway (By similarity).

Mediates ubiquitination and degradation of SMAD1 and SMAD5, 2 receptor-regulated SMADs specific for the BMP pathway (By similarity).

Promotes ubiquitination and subsequent proteasomal degradation of TRAF family members and RHOA (By similarity).

Promotes ubiquitination and subsequent proteasomal degradation of MAVS (PubMed: 23087404).

Plays a role in dendrite formation by melanocytes (By similarity).
