New potential anti-cancer compounds discovered by the Stagljar lab

In the latest issue of Nature Chemical Biology, the Stagljar lab used the mammalian membrane two-hybrid drug screening (MaMTH-DS), a technique that they previously pioneered, to identify new compounds that inhibit the activity of oncoproteins that cause breast cancer. In this case they found four compounds that inhibit the dimerization of the epidermal growth factor receptor (EGFR), which is commonly mutated in non-small-cell lung cancers that have become […]

New details on how cells activate programmed cell death

In the latest issue of Molecular Cell, the Andrews lab provide the first evidence that the complexes of Bcl-2 family proteins, which regulate mitochondrial outer membrane permeabilization and thereby cell death, are not necessarily dimeric.  Instead Bad binds a pre-existing membrane bound hetero-trimer consisting of a dimer of Bcl-XL and one tBid, promoting an allosteric change in the complex that lifts tBid away from the membrane enabling the […]

How bacterial invaders are sensed in the gut

A new paper in the latest issue of Science describes how the bacterial-sensing proteins, NOD1/2, are recruited to the membranes of our gut cells for them to function to initiate a proper immune response. This involves the addition of a lipid, palmitoyl, to NOD1/2 by the palmitoyl-transferase ZDHHC5. Importantly variants of NOD2 that are associated with Crohn’s disease are unable to be palmitoylated.  This work involved an international collaboration […]

Angus McQuibban awarded major funding for anti-neurodegenerative diseases drug discovery by AI

Professor G. Angus McQuibban has just been awarded a $2.3-million Genome Canada grant.

The GAPP grant in a partnership with Cyclica and Rosetta Therapeutics (founded by Professors Angus McQuibban and Peter Lewis) will support drug discovery related to treating people with the long-term neurodegenerative diseases and will involve the use of artificial intelligence and machine learning.

Red Cell Anion Exchanger Makes the Cover of Biophysical Journal

Dario De Vecchis, a post-doctoral fellow in the laboratory of Dr. Antreas Kalli at Leeds, University, in a collaborative project with Reinhart Reithmeier used molecular dynamics simulations to build the first atomic scale model of the red cell anion exchanger in a complex lipid bilayer that mimics the native membrane. This work appeared in the latest edition of the Biophyisical Journal.  The modelling revealed the dynamic nature […]

Pai lab visualize the inner workings of an enzyme

Researchers from the Emil Pai Lab in collaboration with the Miller Lab (Depts. of Chemistry and Physics, University of Toronto) have pieced together a time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. This study, published in Science, is the most detailed depiction of such a process to date.

The communication between the protein units is accomplished via a water-network somewhat akin to a […]

Biochemistry Department Retreat 2019

The 2019 Biochemistry Retreat was a huge success. Members of the department spent September 4th to the 6th up at Geneva Park where they heard talks from students, postdocs, faculty and invited speakers. In the midst of all this, department members partook in a scavenger hunt, fireside singing and other group activities. the department also distributed awards to its trainees for their accomplishments.

Here are some highlights:

Sarah Kronheim from the […]

Enzymatic Activity Regulated by Phase Separation

In the latest issue of Science the Forman-Kay lab demonstrate that as proteins transition from the bulk solution to a phase separated condensate in a test tube, this regulates their ability to affect translation and deadenylation in the same manner observed in the cell. Partitioning of components of the translational machinery away from the mRNA can block translation while the unique condensate environment can activate deadenylation.

A previous dogma […]

The inaugural Proteostasis Researchers in Canada (PRinCE) symposium

The Proteostasis Researchers in Canada (PRinCE) inaugural meeting was held at the University of Toronto on June 10-11, 2019. The aim of this first symposium was to establish a network of researchers working in the field of protein homeostasis in Canada and to promote collaborations between labs working on topics relevant to proteostasis. These include (but are not limited to) protein folding, protein trafficking, protein degradation, and neurodegenerative diseases – […]

Photos from the 2019 Benjamin Schachter Event!

On May 3, 2019, over 200 faculty, alumni, students, gathered at Hart House to celebrate Dr. Benjamin Schachter’s legacy and reunite our Department in appreciation for all of our alumni. Some of the captured moments are shown below…with more photos to come.

Thank-you to all those who attended, planned, participated, and helped make this day a memorable one!
