Microtubule nucleation for spindle assembly: one molecule at a time

J Kraus, R Alfaro-Aco, B Gouveia, S Petry - Trends in biochemical sciences, 2023 - cell.com
The cell orchestrates the dance of chromosome segregation with remarkable speed and
fidelity. The mitotic spindle is built from scratch after interphase through microtubule (MT) …

Augmin is a Ran-regulated spindle assembly factor

J Kraus, SM Travis, MR King, S Petry - Journal of Biological Chemistry, 2023 - ASBMB
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 …

M Zaferani, R Song, S Petry… - Proceedings of the …, 2024 - National Acad Sciences
Controllable platforms to engineer robust cytoskeletal scaffolds have the potential to create
novel on-chip nanotechnologies. Inspired by axons, we combined the branching …

[HTML][HTML] HURP facilitates spindle assembly by stabilizing microtubules and working synergistically with TPX2

V Valdez, M Ma, B Gouveia, R Zhang, S Petry - bioRxiv, 2023 - ncbi.nlm.nih.gov
In large vertebrate spindles, the majority of microtubules are formed via branching
microtubule nucleation, whereby microtubules nucleate along the side of pre-existing …

RanGTP regulates the augmin complex

J Kraus, SM Travis, MR King, S Petry - bioRxiv, 2022 - biorxiv.org
Spindles are composed of microtubules that must nucleate at the right place and time during
mitosis. Spindle microtubule nucleation is regulated by the GTPase Ran, which, through …
