Component of SCF(ASK-cullin-F-box) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins. Protein modification; protein ubiquitination. Part of a SCF (ASK-cullin-F-box) protein ligase complex. The predicted gene At4g35740 has been split into 2 genes: At4g35733 and At4g35740. The predicted gene At4g35740 has been split into 2 genes: At4g35733 and At4g35740.
