Cell cycle transitions are driven by the periodic oscillations of cyclins, which bind and activate CDKs (cyclin-dependent kinases) to phosphorylate target substrates. Cyclin F uses a substrate recruitment strategy similar to that of the other cyclins, but its associated catalytic activity is substantially different. Indeed, cyclin F is the founding member of the F-box family of proteins, which are the substrate recognition subunits of SCF (Skp1-Cul1-F-box protein) ubiquitin ligase complexes. Here, we discuss cyclin F function and recently identified substrates of SCFcyclin F involved in dNTP production, centrosome duplication, and spindle formation. We highlight the relevance of cyclin F in controlling genome stability through ubiquitin-mediated proteolysis and the implications for cancer development.
