Protein
F-box/LRR-repeat protein 15
Organism
Rattus norvegicus
Function
Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of SMURF1, thereby acting as a positive regulator of the BMP signaling pathway. Required for dorsal/ventral pattern formation. Also mediates ubiquitination of SMURF2 and WWP2 (By similarity). Required for bone mass maintenance.
Similarity
Belongs to the FBXL15 family.
