Andrew Neumann, Rytis Prekeris @prekerislab.bsky.social and colleagues discover a leading role for Rap2 in cell migration. Highlight: journals.biologists.com/jcs/article/... Article: journals.biologists.com/jcs/article/... #OpenAccess #ReadandPublish

Want to learn how Rap2 regulates cell migration? Check out our new paper. Great job Andrew! pubmed.ncbi.nlm.nih.gov/41200767/

Ubiquitylation-dependent Rap2 activation regulates lamellipodia dynamics during cell migration - PubMed

Cell migration is a complex process hallmarked by front-to-back cell polarity that is established by the highly dynamic actin cytoskeleton. Branched actin polymerization creates a lamellipodium at the leading edge of the cell, while the contractile acto-myosin cytoskeleton is present at the lagging …

It was a real pleasure to host Daniele Menjivar in my lab as part of CREU program (cancer research experience for undergraduates). It is such a breath of fresh air to be involved in mentoring new generation of scientists, especially in current anti-science environment.

🏅 Congrats to Andrew Neumann, winner of the FEBS Open Bio Poster Prize at the EMBO Workshop “Cell polarity and membrane dynamics” with the work "Mono-ubiquitylation dependent activation and regulation of Rap2 function during cell migration"👏 @prekerislab.bsky.social‬ franbottanelli.bsky.social

Happy Summer Solstice!

Andrew (student in my lab) won best student talk at EMBO conference on cell polarity! Good jib Andrew!

Andrew (PhD student in my lab) is presenting talk and poster in EMBO cell polarity meeting. And he is crushing it!

Off to EMBO cell polarity meeting in San Feliu de Guixol. But first, will spend a day in Barcelona. This is one of my favorite microbreweries there

My self-appointed guards making sure that I am safe while writing grant and drinking wine on patio in our house.

Welcome to the Bluesky account for Stand Up for Science 2025! Keep an eye on this space for updates, event information, and ways to get involved. We can't wait to see everyone #standupforscience2025 on March 7th, both in DC and locations nationwide! #scienceforall #sciencenotsilence

The best way to recover from all the nonsense in last couple weeks is to have lunch near fire pit. 65F temperature and sun also helps.

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...

Slizikai time! These poppy seed mini cakes are made and eaten in Lithuania only on the Christmas Eve. I was waiting entire year for this!

Happy Winter Solstice!

Congrats to Katie Vaeth for her excellent talk at ASCB meeting on our work on RNA targeting to the Midbodies.

Looking forward for ASCB meeting tomorrow, but to start I will enjoy great shrimp tacos with nice IPA.

Please join two sessions of the 8th Frontiers in Cytokinesis Subgroup on Sunday Dec 15 at #cellbio2024!
