the MAYOR LAB.
We are a research lab at the Department of Biochemistry and Molecular Biology at the University of British Columbia. Our aim is to better understand how unwanted and aberrant proteins are eliminated from the cell.
Accumulation of aberrant misfolded proteins lead to their aggregation in the cell and has been link to numerous neurodegenerative diseases like Parkinson’s and Huntington’s.
We like ubiquitin, the proteasome, protein mass spectrometry, yeast genetics, mammalian tissue culture cells and many other ways to investigate protein quality control.
There will an opening for 1-2 PhD positions starting Sep 2019. Prospective students should contact Dr. Thibault Mayor by email with their CV and consult the websites of the Department of Biochemistry and Molecular Biology and of the Genome Science and Technology Program.
There are typically between 1-2 ongoing undergraduate projects at any given time (summer projects, 448/449 directed studies, work-studies or co-op projects). For inquiries, interested students should directly contact Dr. Thibault Mayor by email with their CV and a copy of their transcripts (unofficial).
There is a variety of projects available such as:
- Characterization of the role of ubiquitination in the heat stress response;
- Identification of novel quality control degradation pathways in mammalian cells;
- Characterize how the proteome is affected upon aging and in stress conditions;
- Develop novel proteomic approaches to probe protein homeostasis;
- Utilize experimental evolution in order to modify protein homeostasis.
Deubiquitinase activity is required for the proteasomal degradation of misfolded cytosolic proteins upon heat-stress.
