I love AlphaFoldβ€”but please include PAE (Predicted Aligned Error) plots for every β€œinteraction.” Pretty PDBs β‰  proof. If the PAE doesn’t show an interface, it ain’t one. Show the plots. Structural biology's reputation is on the line.

Why are Ξ±-synuclein aggregates in Parkinson’s disease (PD) toxic at the cell biological level?

Our new study shows that Ξ±-syn fibrils hijack the ESCRT membrane repair system, triggering a feedback loop that worsens aggregation.

Functional assembly starts during translation, and in a surprising way. Although our model protein is a homooligomer, assembly is directional.
One fully-synthesised subunit interacts with an incomplete subunit on the ribosome, avoiding misassembly between two incomplete chains.

By studying a protein that is difficult to fold, we discover fascinating new mechanisms by which the ribosome supports protein biogenesis.
