Just when you think you have it all, Venecia Valdez and team from @RuiZhangWUSTL and @LabPetry prove us wrong: HURP facilitates spindle assembly by stabilizing microtubules and working synergistically with TPX2 biorxiv.org/content/10.1101/…

Follow this thread to get the full story by @meisam_zaferani with Ryungeun Song from Howard STone's lab and @LabPetry on cytoskeletal circuits, our newest development:
Meisam Zaferani@meisam_zaferani3 Oct 2023
Have you ever seen a microtubule (MT) diode?🤯 Exciting news! 🎉 My first postdoc publication is out! With Ryungeun Song, Howard Stone, and @LabPetry, we combined microfluidic, nanofabrication, and branched MT networks to build cytoskeletal circuits. ift.tt/U8pt3hO

This paper is now officially out: Augmin is a Ran-regulated spindle assembly factor: jbc.org/article/S0021-9258(2… Congrats @JodiKraus1 and @sophiembtravis and alumni @MattKingLab from @LabPetry

Augmin is a Ran-regulated spindle assembly factor

Mitotic spindles are composed of microtubules (MTs) that must nucleate at the right place and time. Ran regulates this process by directly controlling the release of spindle assembly factors (SAFs)...
