What a wonderful time catching us with @meghanriddell.bsky.social in Charolette at the Society for Reproductive Investigation Annual Meeting!

Cell biology meets climate resilience – a call to action The molecular and cellular biology community has always been driven by a fascination with mechanisms – how proteins interact, how organelles communicate and how cells respond to stimuli. Yet one of th...

Mónica Bettencourt-Dias @monicabettencourt.bsky.social, Amy Gladfelter @gladfelterlab.bsky.social, Gautam Dey @gautamdey.bsky.social Samara Reck-Peterson @samreckpeterson.bsky.social @cells4planethealth.bsky.social @embo.org share a call to action to apply the lens of #cellbio to climate challenges.

Immiscible proteins compete for RNA binding to order condensate layers Biomolecular condensates mediate diverse and essential cellular functions by compartmentalizing biochemical pathways. Many condensates have internal subdomains with distinct compositional identities. ...

Excited to share our first story on nuclear paraspeckles! Led by @sneadlab.bsky.social, this is the culmination of a ~4 year effort in collab. with @shrinivaslab.bsky.social. Can’t wait to see more paraspeckle stories from the future Snead Lab at Northwestern 🫧 www.biorxiv.org/content/10.1...

Cooperativity in septin polymerization is tunable by ionic strength and membrane adsorption Cells employ cytoskeletal polymers to move, divide, and pass information inside and outside of the cell. Previous work on eukaryotic cytoskeletal elements such as actin, microtubules, and intermediate...

The mysteries of septins continue to unfold in this study examining mechanisms of septin polymerization and assembly! www.biorxiv.org/content/10.1...

Lipid packing and local geometry influence septin curvature sensing Septins assemble into scaffolds that direct cell growth and morphology that are often localized to the plasma membrane. While septins preferentially bind convex membranes via amphipathic helices, thei...

We are excited to share our next installment of insights into how septins sense micron-scale curvature via detecting lipid packing! www.biorxiv.org/content/10.1...

Two weeks left to apply for this year's Physiology Course! We are looking forward to another exciting summer 🔬🦑☀️

Negative feedback equalizes polarity sites in a multi-budding yeast Morphogenesis in fungi and animals is directed by polarization of small GTPases Cdc42 and Rac. In the budding yeast Saccharomyces cerevisiae competition between polarity patches results in one polariz...

New work lead by graduate student Alex shows how concerned signaling networks can be modulated for distinct morphogenic programs even within the constraints of fungal budding! www.biorxiv.org/content/10.1...

RNA encodes physical information Most amino acids are encoded by multiple codons, making the genetic code degenerate. Synonymous mutations affect protein translation and folding, but their impact on RNA itself is often neglected. We ...

Thrilled to share our recent work on the power of RNA to encode physical information and how this can be embedded in the genetic code

Condensates act as translation hubs to coordinate multinucleate cell growth Coordination between growth and division is a fundamental feature of cells. In many syncytia, cell growth must couple with multiple nuclear divisions in one cytoplasm. In the fungus, Ashbya gossypii, ...

Excited to share the latest work from postdocs Ameya
and Zach! We thought about how multinucleate cells are able to maintain N:C ratio, and found a condensate rheostat that regulates translation of cell cycle + growth mRNAs. Check it out! www.biorxiv.org/content/10.1...
