Paper by Zane and Jonathan on microtubule dynamics accepted by JCS

Congratulations to Zane and Jonathan on their paper “Microtubule dynamics regulation reconstituted in budding yeast lysates“, now accepted and online in the Journal of Cell Science.

Recreation of Microtubule Dynamics in Budding Yeast Lysate. A reaction chamber is prepared by adhering GMPCPP-stabilized, rhodamine-labeled porcine microtubule seeds (red) to a glass coverslip through a biotin (black stems)-neutravidin (orange ovals) system. Whole-cell lysate from GFP-tubulin (green) expressing yeast strains is flowed into the chamber and incubated to allow for the polymerization of microtubules. Growth and dynamics of single microtubules is observed by TIRF microscopy in the context of other soluble proteins found in the cell (black shapes).

Goodbye Daphne, Itziar and Emily!

The Drubin/Barnes lab would like to send our fondest farewells to Daphne, Itziar and Emily who are moving on to exciting new positions!

Daphne Dambournet is now working as a Cell line engineer at Memphis Meats working to grow sustainable cultured meat.

Itziar Ibarlucea has taken a position as a post-doctoral associate in the laboratory of Jeffrey Ravetch at The Rockefeller University.

Emily Stoops is now working as a Scientist at Calico where she is working to combat aging.

Paper by Yidi Sun now published in eLife

Congratulations to Yidi, her former and current undergraduates Niki and Tommy, and collaborators in the Darzacq Lab, on their new paper “Switch-like Arp2/3 activation upon WASP and WIP recruitment to an apparent threshold level by multivalent linker proteins in vivo” now published at eLife!

Switch-like activation of the Arp2/3 complex mediated by SH3 domain-PRM mediated interactions during yeast CME.

Paper on Nanoscale curvature manipulation for studying CME published in Nature Nanotechnology

Congratulations to our collaborators in the Cui Lab, Matt Akamatsu, and former lab members Jessica Marks and Alex Grassart on their paper “Nanoscale manipulation of membrane curvature for probing endocytosis in live cells” now published in Nature Nanotechnology.

Vertical nanopillars generate well-defined membrane curvatures that induce local accumulation of endocytic proteins.

Goodbye Jessica!

The Drubin/Barnes lab celebrated post-doc Jessica Marks moving on to her new position as a AAAS Fellow. We wish her all the best in Washington, DC!

Celebration at Brazil Cafe as Jessica moves to a new position a AAAS Fellow in D.C.
