The SCF ubiquitin ligase: insights into a molecular machine

Timothy Cardozo & Michele Pagano

Ubiquitin ligases are well suited to regulate molecular networks that operate on a post-translational timescale. The F-box family of proteins — which are the substrate-recognition components of the Skp1–Cul1–F-box-protein (SCF) ubiquitin ligase — are important players in many mammalian functions. Here we explore a unifying and structurally detailed view of SCF-mediated proteolytic control of cellular processes that has been revealed by recent studies.
