Protein Homeostasis in Neurodegenerative Diseases
Protein aggregation is a hallmark of numerous neurodegenerative diseases including Alzheimer's Disease, Parkinson's Disease, Amyotrophic Lateral Sclerosis (ALS), and the polyglutamine diseases. The Scaglione lab focuses on understanding how protein quality control pathways counteract protein aggregation to maintain neuronal health.
Dictyostelium discoideum have a unique proteome that contains ~10,000 homopolymeric amino acid repeats. Among the most common repeats is glutamine, the amino acid repeat that causes a class of nine neurodegenerative diseases. The Scaglione lab focuses on understanding how Dictyostelium's protein quality control network suppresses polyQ aggregation.

9/2016- Congratulations to Adam Kanack on receiving the Peter G. Pentchev Fellowship from the National Piemann-Pick Disease Foundation! Adam will be focusing on developing strategies to inhibit ubiquitination of NPC1.
Protein degradation by the ubiquitin-proteasome system is one mechanism neurons utilize to clear aggregation prone proteins. The Scaglione lab is interested in understanding the mechanism of ubiquitin transfer to allow development of methodolgies to hi-jack the ubiquitination machinery.
