Some news... This week I passed my PhD viva with no corrections! A big thank you to my examiners @KathaSchmack and @magnetokrishio for such an inspiring discussion, and to my amazing supervisors @dr_rick_adams, @DanHauke and Karl Friston for all their support throughout my PhD!
Just submitted some designed proteins to @adaptyvbio EGFR binder competition. My strategy was Chai1 optimization on a diverse set of known EGFR binders shown below. Lower 2 are antibody FABs (necitumumab and panitumumab) which are too large for the competition requirements so...
Imagine a dataset where it's the whole of the AlphaFold Database but you can pull-out the domain-like structures avoiding random spaghetti, or get all the domain-domain interactions, or check whether domains match a known structural super-family. That's TED:

TED: The Encyclopedia of Domains now published in @ScienceMagazine discovering and annotating 314 MILLION protein domains in the AlphaFold database. joint work of @CATH_Gene3D and @psipred here at UCL.
Chai1 (open source version of AlphaFold3) installed in 5 mins and generates preds for this protein-protein + mol glue complex in 2 mins on a 3090. amazing.
Our paper now published: Chainsaw predicts domains in protein structures. We combine this with homology detection to infer functional annotations for previously uncharacterised proteins in AlphaFold DB, we also...

The Encyclopedia of Domains identifies over 320M structural domains in the AlphaFold Database, including many not in CATH and other PDB-based databases.

Ever wondered how closely #fMRI brain networks reflect a neural underpinning❓
We address this using simultaneous fMRI & widefield Ca²⁺ imaging in mice, and the answer is… complicated!

Jointly supervised by @EvelynMRLake & @PessoaBrainnature.com/articles/s4146…
A Review in @ScienceTM looks at the complex connections between astrocytes and other types of cells in the nervous system, including neurons, oligodendrocytes, and microglia.
