We are thrilled beyond words to see our LYCHOS (GPR155) publication out today in @Nature. 🥳
“LYCHOS is a human hybrid of a plant-like PIN transporter and a GPCR”

Sometimes projects have a particular hurdle - this project had an avalanche. Every stage of the investigation was tough; cloning, purifications, freezing, analysis, function. This figure highlights the #cryoEM analysis.
Earlier this year, I was incredibly honoured to receive the Premier’s Award for Health and Medical Research in the Basic Science category.
This recognition is a huge testament to the amazing work of our entire team. 🙌💥🎉

Amidst the chaos, here's a belated but exciting highlight on the recent LYCHOS structure by @bj_charles@LuptonCJ @Dr_Ellisdon @Dr_MLHalls@RobertoZoncu and I broke down their findings, explored future directions, and tackled the key remaining questions.

The first major body of work from my PhD is now up on BioRxiv!
We used AI-designed binders to block the uptake of heme from hemoglobin through ChuA, a heme transporter found in pathogenic E. coli. 🦠🩸🔬
I’m very grateful for my supervisors and all coauthors for their support!
@chaidiscovery I'm come across a rather perculiar behaviour. Chai1 correctly models a complex fold when provided Cα-Cα constraints (as little as 2% work) with use_esm_embedding=False. However if I alter the sequence by even a single residue, the prediction fails... Any insight?
@allostericstate @MonashBDI@MonashUni@CryoEM_Monash@HariVenugopal2 Thanks TJ - it certainly wasn't. We learnt the hard way that TSC is also quite prone to denaturing due to AWI issues and freezing. Not a trivial problem 😅 but we persevered and had fun!
🚨 Our story on the TSC:WIPI3 lysosomal-recruitment complex is now live in @ScienceAdvances .

Finally TSC is extraordinarily flexible and is a massively difficult structural biology target. We had to use all the tricks we know to get this one... Parts of TSC can move by up to 10 nm!!!
