Congratulations @meisam_zaferani and Ryungeun! We are proud of you.
Our work is now online at @PNASNews! ๐ฅณ https://t.co/nTaZCItBSy This was a fantastic collaboration with my teammate, Ryungeun Song. A big shout-out to Howard Stone and @LabPetry for their superb mentorship throughout this journey. @omenndarlingbio @EPrinceton @PrincetonMolBio

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 https://t.co/u5n9UjAnAZ

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:
Have you ever seen a microtubule (MT) diode?๐คฏ Exciting news! ๐ 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. https://t.co/2MpFCn1XCt

Terrific work by Changmiao Guo and Ray Alfaro-Aco from @TatyanaPolenova and @LabPetry: Structural basis of protein condensation underlying branching microtubule nucleation
nature.com
Nature Communications - TPX2 is a key factor stimulating branching microtubule (MT) nucleation. TPX2 forms condensates on MTs critical for branching. In this work, the authors report the...

This paper is now officially out: Augmin is a Ran-regulated spindle assembly factor: https://t.co/KugwLDom3N Congrats @JodiKraus1 and @sophiembtravis and alumni @MattKingLab from @LabPetry
jbc.org
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)...
