Festival of Lights – Dec 2021

To cap off the end of 2021, the Teves lab went on an outing to see the fantastic Festival of Lights at the VanDusen Botanical Garden. The park is transformed into a wintry fairy-tale garden, with each area showcasing different themes through magical show of lights. Highly recommended!

Lab Photo 2021

November 23, 2021. It’s been over a year since we last gathered for a group photo. So here we are! Still growing stronger together.

Our most recent work, led by James Kwan and Thomas Nguyen, is now out on BioRxiv

Ever wonder how Pol II transcription starts? So did many several decades ago. Works from Roeder, Hahn, Buratowski, Tjian (and so many more) have ironed out the mechanism of Pol II recruitment and initiation in eukaryotic cells. And these are literally in the textbooks.

At the center of it all is this one protein called TBP. An essential gene, TBP is conserved throughout Archaea and Eukarya. Without it, you don’t get transcription… Or do you???

Well, for reasons we won’t get to for now, we decided to revisit TBP, even though it seemed like it was all figured out a while ago. What we found blew our minds. Turns out, at least in mouse embryonic stem cells, Pol II doesn’t need TBP to transcribe genes!

mouse ES cells don’t even need TBP to induce transcription of silent genes! So what is going on? Read all about it here!

Congratulations to all members of the Teves lab, especially James and Thomas who spearheaded this project together.
