Our paper on katanin regulation by the tubulin code is out! Tubulin glutamylation and glycylation act combinatorially and antagonistically to regulate microtubule severing Congratulations Ewa, Elena, Steven and Kishore and special thanks to Yan Li for mass spec analyses!

Stephanie was awarded a PRAT postdoctoral fellowship!  Congrats Stephanie!!!

Congrats to Beth for her NINDS postdoctoral fellowship award! Go Beth!

We received a NIH director's innovation challenge award in collaboration with Hari Shroff and AIM to obtain a 4D map of the tubulin code in human neurons! Multiple positions open!

Kishore was selected as a speaker at the "Rising Stars in Cell Biology" Symposium at Johns Hopkins.

Stephanie was awarded a postdoctoral fellowship from NINDS. Congratulations Stephanie!

Antonina is the 2023 recipient of the International Award from the Biochemical Society. Read more about it here.

ER navigates the cell using the tubulin code! Our new collaborative paper with the Lippincott-Schwartz and Blackstone labs is out! [abstract]

Congrats to Ilia for his F32 fellowship award from NINDS!


Jiayi's microtubule comets design is pictured on the cover of Developmental Cell.

Cells have microtubules populations with distinct dynamics. How does this asymmetry arise? Check our recent paper in which we show that tyrosination specific recruitment of regulators at the microtubule ends regulates microtubule dynamics creating microtubule populations with distinct dynamics in cells. Massively fun collaboration with Nikita Gudimchuk and his team on molecular dynamics. Check it out, as well as the nice Preview. Congratulations Jiayi and Aga! 

Our paper on the mechanism of poly-Glu chain initiation and elongation is out in Nature Structure and Molecular Biology! Fantastic collaboration with Nico Tjandra’s lab at NHLBI and Martin Tanner’s lab at UBC with expert mass spec help from our own Yan Li! C. From inhibitors to structure to enzymatic mechanism. Congrats Kishore, Keith, Maddie and Yanjie!


Kishore's paper with the Reber Lab is out in Current Biology!

Jiayi was awarded an NINDS postdoctoral fellowship. Congrats Jiayi!

Our paper on the cryo-EM structure of katanin bound to the tubulin tail is out in Dev. Cell! Congratulations Elena, Ewa and Aga!


Annie gave a great talk on lattice tubulin exchange by severing enzymes at Biophysics.


Our paper showing that microtubule severing enzymes promote tubulin exchange within the microtubule is out in Science! Congratulations to Annie, Ewa, Elena and Jeff!


Antonina was selected as the 2017 Keith R. Porter fellow! Honored and excited to receive the award from Erika Holzbaur at ASCB. Looking forward to thinking about ways to draw the public and students into the beautiful world of cell biology!
