Background of the antigen
FBXO4 is a 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 target proteins. It probably recognizes and binds to phosphorylated target proteins. It recognizes TERF1 and promotes its ubiquitination together with UBE2D1.
