I'm very proud that our paper, and with that the main project of my PhD, has just been published by @natcomms.nature.com! 🎉
Here, we reveal the unique, molecular mechanism by which USP1/UAF1 cleaves ubiquitin chains on PCNA, which may direct DNA damage tolerance.

USP1/UAF1 targets polyubiquitinated PCNA with an exo-cleavage mechanism that can temporarily enrich for monoubiquitinated PCNA - Nature Communications
DNA damage tolerance is regulated by ubiquitination of PCNA. Here, the authors present kinetic and structural studies showing that USP1/UAF1 prefers trimming K63- and K48-ubiquitin chains down over cl...

This seems like a pretty big deal
We did it! We caught Starship #transposons moving between #fungal species in the lab, including between species separated by ~100my. We think Starships are a mediator of HGT in fungi, akin to conjugative elements in bacteria. Check out the preprint. www.biorxiv.org/content/10.1...

I wonder if my American friends understand the acute sense of collective betrayal we are experiencing in Canada right now. It's widespread and deeply felt.

The big 4 of grant writing:
1. Credibility: The topic fits your expertise
2. Narrative: It's clear what is the problem, the solution, and why you’re the right person for it
3. Juicy details: Flex your mastery of the topic
4. The concept: You connect every part to the big question

Excited to share that my main PhD project has been published! 🎉 We systematically designed and optimized reporters for 86 transcription factors in parallel. If you're interested in using these optimized reporters for your own research, don’t hesitate to reach out!
Optimized reporters for multiplexed detection of transcription factor activity
Direct measurements of transcription factor (TF) activity are crucial for understanding how TFs interpret signals and drive gene expression. TF reporter constructs have been widely used to detect activity in cell signaling, developmental biology, and disease models. However, many mammalian TFs lack reliable reporters. In this study, a library of reporters for 86 TFs was designed and evaluated to identify optimized “prime” TF reporters.
