The Centrosome Is a Selective Condensate that Nucleates Microtubules by Concentrating Tubulin – congratulations to Jeff Woodruff and colleagues on their paper in Cell!

Our latest publication is out now in Cell! In this work, led by Jeff Woodruffwe used defined components to reconstitute a minimal centrosome in vitro that can nucleate microtubule asters.  Our results suggest that the centrosome acts a selective phase that nucleates microtubules by concentrating microtubule polymerases and soluble tubulin.

Stem cells: the new “model organism”

In a new perspective published in Molecular Biology of the Cell, Tony Hyman and David Drubin “argue that combined advances in genome editing, stem cell production, and organoid derivation from stem cells represent a revolution in cell biology.”  These technological advances mean that stem cell studies could now replace molecular and cell biology studies traditionally carried out in human tissue culture cells, which have significant genome abnormalities and do not represent a normal physiological state. Read more in the full article in MBOC.

An aberrant phase transition of stress granules triggered by misfolded protein and prevented by chaperone function

New work from the Hyman and Alberti labs uncovers an important role for chaperone proteins in preventing aberrant phase transitions in stress granules. See a brief synopsis below and read the full paper online. Congratulations to all of the authors on this work!

Synopsis

The presence of misfolded protein in stress granules alters their dynamic state and induces a phase transition. This process is counteracted by chaperones and autophagy, acting as a stress granule quality control system.

  • Misfolded proteins have a tendency to aggregate in stress granules (SGs).

  • Misfolded proteins promote a conversion of SGs into an aberrant solid‐like state.

  • Chaperones prevent the formation of aberrant SGs and promote SG disassembly.

  • Persistent aberrant SGs are targeted to the aggresome for degradation.
