Temporal tuning of actin nucleation by the repurposed DNA repair complex RAD51/fignl1 encodes distinct axon guidance decisions

Samya Zerkoune, Yvrick Zagar, Julie Delaroche…·Coralie Fassier

The paper shows how RAD51/fignl1, repurposed from DNA repair, controls axon guidance by modulating F-actin nucleation timing and magnitude.

Huntingtin bundles and changes the local proteome of actin filaments in neurons

Rémi Carpentier, Jaesung Kim, Mariacristina Capizzi…·Sandrine Humbert

This study shows that Huntingtin (HTT) binds to F-actin, bundles actin filaments, and modulates the association of Drebrin1 with actin, affecting axonal growth and cytoskeletal organization in neurons.

The Mn-motif protein MAP6d1 assembles ciliary doublet microtubules

Dharshini Gopal, Juliette Wu, Julie Delaroche…·Isabelle Arnal

This study identifies MAP6d1 as a microtubule-associated protein that assembles ciliary doublet microtubules by recruiting tubulin dimers and promoting luminal protofilament formation.
