Research will continue to focus on the function of the ubiquitin protein ligase E6AP that is deficient in patients with Angelman Syndrome. About 10% of the AS patients harbor missense mutations in the coding region of the UBE3A gene. For most of these mutations it is currently unclear how these mutations disrupt E6AP function. We have introduced these AS missense mutations in the UBE3A gene and will test the effect of these mutations on target protein binding, ubiquitin protein ligase activity, stability and in vivo function. Recently, we obtained evidence that E6AP activity can be modulated by external factors. We have constructed tailored brain cDNA libraries that will be used in genetic screens to identify novel cellular activators of E6AP. Finally, we have converted the bacterial ubiquitination system to a proteome-wide method that allows us to screen a brain cDNA expression library for proteins that are ubiquitinated by E6AP. These systematic approaches aimed at identification and characterization of E6AP targets and understanding how E6AP activity is regulated will not only provide fundamental insight into the pathophysiology of AS but may also reveal potential targets for therapeutic strategies.
