Reposted by Jane Coffin Childs Fund for Medical ResearchAmir Bitran @amirbitran.bsky.social · 05/07/2026In summary, the ribosome uses diverse strategies to regulate protein folding, dependent not just on folding thermodynamics, but also kinetics + coupling to elongation. In the future, can extend this to study how co-translational folding links to evolutionary fitness and misfolding disease. (11/n) 131
Reposted by Jane Coffin Childs Fund for Medical ResearchAmir Bitran @amirbitran.bsky.social · 05/07/2026Notably, this minimal co-translational folding isn’t because HaloTag CAN’T fold on the ribosome, but rather it doesn’t have time to! When we artificially stall translation and give the nascent chain time to reach equilibrium, it actually populates an intermediate similar to that in refolding! (9/n) 131
Reposted by Jane Coffin Childs Fund for Medical ResearchAmir Bitran @amirbitran.bsky.social · 05/07/2026But something wildly different happens for HaloTag, which attains higher folding yield when translated vs refolded from denaturant. Turns out HT hardly folds on the ribosome, showing only weak HDX protection But once released, it folds through a different intermediate than when refolded! (7/n) 111
