New publication with Chantal Prévost and @sacquin-mo.eurosky.social is out in JPCB ! We show with all-atom MD simulations that disordered alpha-tubulin C-terminal tails wrap around the proline-rich region of the Tau protein, but not so much around its repeat domains pubs.acs.org/doi/10.1021/...

Simulations of an Extended Tau/Tubulins Interface Reveal a Complex Disorder–Disorder Interplay Mediated by the C-Terminal TailsBuilding on a complex between a tubulin protofilament (PF) and a fragment of the Tau protein containing residues 169 to 367, we investigate the dynamics of the disordered elements of the system, namely the tubulin C-terminal tails (CTTs) and the Tau protein, using classical all-atom molecular dynamics simulations. Our results show that CTTs adopt a hook-like dynamic pattern on the bare PF while remaining highly mobile. The binding of Tau on the PF surface alters the dynamics of the αI-CTTs in a sequence-dependent manner. While the repeat domains of Tau are mostly maintained on the PF by weak and strong binding patches with the tubulin cores, the Proline-Rich Region (PRR) relies on the wrapping phenomenon of αI-CTTs to fuzzily stabilize its interaction with the PF. Our study thus provides a deep dive into the dynamic interplay between the Tau protein and the CTTs of microtubules, the latter being characterized extensively using a variety of disorder-adapted metrics.pubs.acs.org

This is very well done, I think: leidendeclaration.ai A few choice quotes, that should be of interest well beyond mathematics: >>

Leiden Declaration on Artificial Intelligence and MathematicsThis declaration calls for action to address the challenges posed by the use of artificial intelligence within mathematics research.leidendeclaration.ai

Weeks ago, @chanda.blacksky.app sent me this declaration, written and signed by a bunch of mathematicians. But I only had time to read it yesterday, which ended up being right on time given a new round of hype falling exactly under the patterns this document notes.🧵 leidendeclaration.ai
