Our new preprint describes Plasmodium NEK4 as a key regulator coupling meiotic initiation and morphogenesis—a critical step for malaria transmission. This involves MTOC-driven nuclear movement strikingly analogous to "horsetail" movement in fission yeast.

New work on ARK1 (AURKB?) in Plasmodium (malaria parasite) with @ritatewari.bsky.social and Pushkar Sharma. CPC in Plasmodium is (ofcourse..) different compared to conventional models: two INCENPs, no borealin/survivin - mainly at spindle microtubules/MTOCs. Special thanks to @ryanase.bsky.social!
Pleased to share our new preprint: "Plasmodium ARK1 regulates spindle formation during atypical mitosis and forms a divergent chromosomal passenger complex". Many thanks to our collaborators.

Happy to share the first story from my postdoc in @schnittger-lab.bsky.social
We studied TITAN9, a Csm1-like protein in Arabidopsis.
Even though I now work with soil, chromosome segregation and meiosis still have a special place in my heart.

So excited to share this preprint from the Rosin lab in collaboration with the Hawley lab and @eelcotromer.bsky.social on moth spermatogenesis! We investigate the meiotic errors that occur during the formation of apyrene sperm (that have no DNA) in silkworms!

Programmed meiotic errors facilitate dichotomous sperm production in the silkworm, Bombyx mori
The goal of meiosis is typically to produce haploid gametes (eggs or sperm). Failure to do so is catastrophic for fertility and offspring health. However, Lepidopteran (moths and butterflies) males pr...
