Abstract: The present invention relates to binding pockets of Skp1-Cdc53/Cullin-F-box protein (SCF) E3 ubiquitin ligases associated with substrate selection and/or orientation. In particular, the invention relates to a crystal comprising such binding pockets. The crystal may be useful for modeling and/or synthesizing mimetics of a binding pocket or ligands that associate with the binding pocket. Such mimetics or ligands may be capable of acting as modulators of the interactions of a SCF E3 ubiquitin ligase and its substrates, and they may be useful for treating, inhibiting, or preventing diseases modulated by such interactions. Methods are also provided for regulating a SCF E3 ubiquitin ligase comprising changing a binding pocket associated with substrate selection and/or orientation.

Abstract: The invention relates to methods for identifying compounds that modulate ubiquitin-dependent proteolysis, and compounds identified using the methods. The invention also relates to a novel peptide motif referred to as the “CPD motif”, molecules derived from the CPD motif, and uses of the CPD motif and molecules.
