How do cells keep their #actin “highways” stable?🚦
Our paper @PLOS Genetics reveals surprising teamwork (and backup plans!) between tropomyosin isoforms in yeast. #imaging #cytoskeleton #celldivision
This work was brilliantly led by @anubhavdhar.bsky.social @bagyasree.bsky.social

Our latest preprint on the role of the Arp2/3 complex in mitotic entry is now available @biorxiv. This work was done by Dhanya Kalathil, a very talented postdoc in my lab. The story started in 2019 when we were investigating the role of branched actin in cytokinesis. 1/

Hi I’m @yamini-ravichan.bsky.social , a postdoc interested in the mechanical induction of topological defect-mediated morphogenesis. I use different organisms to study the role of topological defects shaping development & regeneration. Below is an insight to the field!

Actin ❤️

Dylan Burnette @mag2art.bsky.social · May 19

The leading edge of a crawling cell videoed through a microscope. Watch the actin cytoskeleton in motion as it drives membrane protrusion and cell movement. It’s like watching the cell think with its feet. #CellBiology
