I'm excited to tell you about the most recent preprint in my lab, demonstrating that a conserved spindle matrix protein, NPP-21/TPR, is required for the stronger checkpoint in germline cells during embryogenesis in C. elegans

Ana Pinto Teixeira @carlos-conde.bsky.social showed that excessive MPS1 activity drives CIN by promoting an untimely expansion of the fibrous corona, providing a structural basis for merotely and chromosome missegregation in colon cancer. #SpindleCroatia2026

Drosophila border cells are beautiful to watch… but far from easy to image. Kudos to the brave and skilled @vitoryang.bsky.social, who took on the challenge of establishing border cell migration imaging in the lab! His movies are astonishing, and now our first-ever study on #cell #migration is out!

New paper alert! In this study, we find that cells with chromosomal instability (CIN) secrete more extracellular vesicles (EVs). These CIN-induced EVs promote migration and invasion of EV-recipient cells an EFEMP1-dependent manner both in vitro and in vivo. link.springer.com/article/10.1...

The conference “Mitotic spindle: From living and synthetic systems to theory” is open! www.phy.pmf.unizg.hr/~mitosis/ Follow us #SpindleCroatia2026!

Only two days to go until the “Mitotic Spindle: From Living and Synthetic Systems to Theory” meeting in Dubrovnik! This is the 4th time Nenad Pavin and I are organizing it, and it keeps growing with each edition. Can’t wait to see everyone in Dubrovnik! shorturl.at/35Vff

Chromosomes stuck behind the spindle are ticking time bombs for aneuploidy. We uncovered a mechanical rescue mechanism where microtubule pivoting repositions these high-risk chromosomes! Out last week in @natcomms.nature.com, here's a thread 🧵 shorturl.at/OD89x

🚨🚨 New preprint 🚨🚨 We found that the ovary directly controls protein appetite in Drosophila. Yes — the ovary doesn’t just make eggs… it tells the fly what to eat! www.biorxiv.org/content/10.6... If you want all the details, click above ☝️ If you just want the fun, GIF-guided overview, keep reading 👇

We finally managed to write Ikers master thesis project together. Interesting and careful work on FAM122A. www.biorxiv.org/content/10.6...

Happy to see the first paper from the lab published in the EMBO J today: link.springer.com/article/10.1... In it, we reconstitute self-assembling cooperative oligomers of human Ndc80 and Ska kinetochore complexes that stabilise microtubule ends, and study these samples using cryoET and TIRF

So happy to share RBI’s news on our new paper in @natcomms.nature.com!

Join us for a wonderful interaction with the virologist MJ Amorim at the CBR. Virus are helping us to uncover fascinating cell biology of centrosomes and cilia, and at the same time better understand host-pathogen interactions and how those can be targeted. Please spread to those interested!

Happy to see our work on defining a dependency map of short linear motifs out. We use base editing screens to install more than 80000 mutations into SLiMs in more than 4000 proteins to determine their contribution to cell fitness. www.nature.com/articles/s41...

We have started a project trying to predic the interactions/structures of all yeast protein pairs using an AlphaFold pooling approach. We are making the current dataset open and we welcome collaborations. www.evocellnet.com/2026/03/mapp...

I had fun writing this N&Vs on two fascinating new papers on centromere evolution in yeast. If you’re interested in how centromeres adapt yet stay functional, here’s my take. rdcu.be/e6DD0 @nature.com @gautamdey.bsky.social @gsherloc.bsky.social @helsenjana.bsky.social @maxhaase.bsky.social

PhD position in my lab!

Mitosis has a timing system. If chromosomes attach properly, cells divide on schedule and keep proliferating. If attachment is slow or incomplete, the delay is recorded — and daughter cells stop dividing. We explore this link in our new preprint. 🔗 www.biorxiv.org/content/10.6...

The discovery of the first kinetochore proteins (CENP-A, CENP-B, CENP-C) was reported by Bill Earnshaw and Naomi Rothfield in 1985 in Chromosoma. Forty years later, Chromosoma/Chromosome Research has published a special issue (most articles are open access) link.springer.com/collections/...
