Vancouver Bioinformatics Users Group

VanBUG (Vancouver Bioinformatics Users Group) is an association of researchers, other professionals and students in the B.C. Lower Mainland who have an interest in the field of bioinformatics.

VanBUG meets on the second Thursday of every month from September through April. Research presentations by bioinformatics leaders, students and industry representatives are followed by networking over pizza and refreshments

Meetings are held in the Gordon and Leslie Diamond Family Theatre, BC Cancer Research Centre, 675 West 10th Avenue at 6:00 pm and are free and open to all.

As a service to the community, other bioinformatics events are posted to the Calendar
Visit our sister groups for bioinformatics events in Montreal (MonBUG) and now Toronto (TorBUG)!

Derek R. Dee

Talk Title: Protein aggregation: from prions to food protein nanofibrils

Date/Time:
Thursday, October 31st, 2019 6:00pm

Affiliation:
Assistant Professor, The University of British Columbia

Bio:
Derek Dee joined the Faculty of Land and Food Systems in January 2019 as an Assistant Professor in Food Science. His research focuses on understanding protein structure and function, and its potential applications in food, biomaterials and medicine.

Dee’s research is an unusual combination of food science and biophysics. His research involves a variety of biochemical, molecular biology and biophysical approaches and offers a training environment that blends basic and applied sciences to better understand and utilize food proteins and enzymes.

His potential collaborators are food scientists, physicists, and computer simulation specialists. One of his current projects is the genetic modification and engineering of protein nanofibrils. Protein nanofibrils are threads of protein only a few molecules wide yet a thousand times longer. They have unique properties which motivate research into how to mimic nature and create new functional materials.

Abstract:
Proteins can adopt various conformations, including native, unfolded, misfolded, and aggregated states. The aggregates can be amorphous or well-ordered, such as amyloid fibrils. In certain cases, fibril formation is associated with disease (e.g., prion diseases, Alzheimer’s, Parkinson’s, and ALS). In a growing number of cases, proteins form amyloid fibrils as part of their natural role, serving as functional amyloid. Potentially any protein can be induced to form amyloid-like fibrils, also called nanofibrils. Nanofibrils hold promise for applications ranging from biosensors, nanowires, cell scaffolding, and, perhaps, as food ingredients. The mechanisms of protein aggregation must be better understood in order to prevent amyloid formation, in the case of disease-associated amyloid, or such that it can be controlled, in the case of engineering functional nanofibrils. In this talk, I will describe how a single-molecule approach, using optical tweezers, can be used to map misfolding and aggregation pathways, and how protein nanofibrils may be used in food.
