Systematic Discovery of Motif-based Interactions of the Auxiliary Domains of USP Family Deubiquitinases

And of course, we could not have done this without NIH funding that has been critical for supporting my students’ training and my career, and for giving us the resources to shed light on some aspects of the molecular basis of human diseases.
Excited to see this paper out in its final form, and huge congrats to first author Ziyuan (Jason) Jiang just a week before his thesis defense. This work has become an invaluable resource in our lab for SHP2 projects, and we hope it resonates with the whole field.
