we report the X-ray structure of the human FBxo3 ApaG domain, residues 278-407, at 2.0 A resolution
AIRE, which is phosphorylated on two specific residues near its N terminus, then binds to the F-box protein 3 (FBXO3) E3 ubiquitin ligase. In turn, this SCF(FBXO3) (SKP1-CUL1-F box) complex ubiquitylates AIRE, increases its binding to the positive transcription elongation factor b (P-TEFb), and potentiates its transcriptional activity.
Fbxo3 promotes the proteasomal degradation of Smurf1. Fbxo3 promotes the poly-ubiquitination of Smurf1.
Virulence factor NSs of rift valley fever virus recruits the FBXO3 to degrade subunit p62 of general transcription factor TFIIH.

Fbx3 formed SCF(Fbx3) ubiquitin ligase and promoted the degradation of HIPK2 and p300 by the ubiquitin-proteasome pathway
AIRE, which is phosphorylated on two specific residues near its N terminus, then binds to the F-box protein 3 (FBXO3) E3 ubiquitin ligase. In turn, this SCF(FBXO3) (SKP1-CUL1-F box) complex ubiquitylates AIRE, increases its binding to the positive transcription elongation factor b (P-TEFb), and potentiates its transcriptional activity.
This gene encodes a member of the F-box protein family which is characterized by an approximately 40 amino acid motif, the F-box. The F-box proteins constitute one of the four subunits of the ubiquitin protein ligase complex called SCFs (SKP1-cullin-F-box), which function in phosphorylation-dependent ubiquitination. The F-box proteins are divided into 3 classes: Fbws containing WD-40 domains, Fbls containing leucine-rich repeats, and Fbxs containing either different protein-protein interaction modules or no recognizable motifs. The protein encoded by this gene belongs to the Fbxs class. Alternative splicing of this gene generates 2 transcript variants diverging at the 3' end.
