James and Selena's paper is out in @jcb.org ! We present a structural model of the TACC3-ch-TOG interaction. Using Affimers that can inhibit this interaction, we uncovered a new role for TACC3-ch-TOG in maintaining the pericentriolar material during mitosis. 🧪 1/n doi.org/10.1083/jcb....

Unique opportunity to join the CytoMorpho Lab (in Paris ❤️) as a postdoc to work on the self-organization and polarization of reconstituted networks made of microtubules, motors and actin filaments in vitro. Experience required. Please Repost 🙏 thanks !

The #nucleus contains the info of a #cell, but it does much more than that !! Since the nucleus is big, acts as the main intracellular obstacle, and during #CellMigration can get 'trapped'/stuck until the cell pushes it FWD. #scicomm @focalplane.bsky.social @cellcommlab.bsky.social #Skyscience

Deeply saddened by the passing of Prof. Mike Sheetz, a true leader in Mechanobiology. His groundbreaking work on Kinesin, membrane organization, and mechanotransduction has left an indelible mark. A tremendous loss to science. #Mechanobiology #Science #LaskerAward

What a sad news. Steve was an outstanding scientist and contributed greatly to midbody and centrosome biology. He was also a great colleague and an accomplished mountaineer. I will miss our scientific discussions and great hikes we did in Colorado. www.mercadantefuneral.com/obituaries/s...

Human Duchenne Muscle Stem Cells do indeed undergo myogenesis when they are myogenic, but they loose their myogenic nature faster than cells from normal muscle. Epigenetic driven. Happy to share our last study in collaboration with Jeff Dilworth in www.cell.com/iscience/ful...
