Supplementary information

SMURF1 also known as SMAD-specific E3 ubiquitin protein ligase 1 functions as an E3 ubiquitin ligase involved in the targeted degradation of proteins. This protein weighs approximately 72 kDa and expresses primarily in various human tissues including bone lung and kidney. SMURF1 plays an essential role in regulating protein turnover by tagging substrates for proteasomal degradation. It interacts with substrates through a C2 domain which aids in membrane localization and substrate recognition effectively controlling cellular protein levels and their functions.
Biological function summary

SMURF1 influences numerous cellular processes such as bone morphogenetic protein (BMP) signaling by regulating the availability and stability of signaling molecules. It does not function in isolation; it is a component of a ubiquitin-proteasome system complex that includes other cofactors assisting its activity. SMURF1 therefore affects cell growth differentiation and homeostasis by managing signal transduction pathways critical for these cellular activities.

Pathways

SMURF1 is involved in the BMP and Wnt signaling pathways. Both are fundamental for various biological activities including embryonic development and cell cycle regulation. Within these pathways SMURF1 influences the activity of SMAD6 and related proteins modulating their turnover and impact on downstream signaling processes. These pathways also interact with other cellular pathways but SMURF1's specific role remains concentrated on modulating protein ubiquitination events.

SMURF1 has been linked to cancer and osteoporosis. Its dysregulation can disrupt normal cellular signaling contributing to tumorigenesis or impaired bone maintenance. In cancer its interaction with proteins such as SMAD7 can alter cell signaling promoting uncontrolled cell growth. In osteoporosis SMURF1's regulation of bone remodeling processes might be compromised leading to decreased bone mass and fragility. Understanding SMURF1's roles may open avenues for therapeutic interventions in these disorders.

Target data

E3 ubiquitin-protein ligase that acts as a negative regulator of BMP signaling pathway. Mediates ubiquitination and degradation of SMAD1 and SMAD5, 2 receptor-regulated SMADs specific for the BMP pathway. Promotes ubiquitination and subsequent proteasomal degradation of TRAF family members and RHOA. Promotes ubiquitination and subsequent proteasomal degradation of MAVS (PubMed : 23087404). Acts as an antagonist of TGF-beta signaling by ubiquitinating TGFBR1 and targeting it for degradation (PubMed : 21791611). Plays a role in dendrite formation by melanocytes (PubMed : 23999003).
