JFK, a Kelch domain-containing F-box protein, links the SCF complex to p53 regulation

Abstract excerpt

The p53 tumor suppressor plays a central role in integrating cellular responses to various stresses. Tight regulation of p53 is thus essential for the maintenance of genome integrity and normal cell proliferation. Currently, several ubiquitin ligases, including the single-subunit RING-finger types--MDM2, Pirh2, and COP1--and the HECT-domain type--ARF-BP1--have been reported to target p53 for degradation. Here, we...
