Pei Yee
@impeiyee.bsky.social
Cell biologist. Postdoc at Urbé/Clague lab. Previously at UCL-LMCB.
Fascinated by ubiquitin biology and membrane trafficking.
Pinned
Deeply honoured to receive the 2025 Raff Medal!
Huge thanks to @bscb-official.bsky.social for the recognition. This wouldn’t have been possible without the support of my supervisors, Sylvie Urbé & Mike Clague, my colleagues, collaborators, and the many mentors who inspired me along the way.
Our latest preprint is out!
We developed an inducible “RapTag” system that uses ENTAC to chemically recruit USP15 to the unstable protein CTLA4. This induced proximity stabilises and slows down the rapid lysosomal turnover of CTLA4.

Targeted recruitment of USP15 enhances CTLA4 surface levels and restricts its degradation.
Induced protein proximity offers powerful new routes to modulate protein fate. While proteolysis-targeting chimeras (PROTACs) promote degradation through E3 ligase recruitment, the converse principle-...

Our review "Proteostasis of immune checkpoint receptors" is out in Biochem J! @biochemsoc.bsky.social

We highlight how ubiquitylation acts as a key sorting signal, governing the fate of immune checkpoints - from the highly stable PD-L1 to the short-lived CTLA-4.
