We quantitatively evaluated the swimming and flagellar movement of Chattonella, a red-tide alga.
Chattonella has two unequal flagella, and we found a positive correlation between anterior flagellum length and swimming speed. #protistonsky

Safely back in Hokkaido! Had a wonderful time at #GloBIAS2025 in Kobe.
The atmosphere of mutual support was fantastic!
Huge thanks to everyone who interacted with me!

Asked similar question before but I try again. Anyone knows proteins that localize like this? This protein is present in diplonemids/bodonids/euglenids/Naegleria, which have two flagella, but not in trypanosomatids that have just one flagellum. Potentially interesting for flagella/cilia community?

Interesting. Iโ€™m not very familiar with Alphafold, so I didnโ€™t know that.

Itโ€™s interesting that all versions of Alphafold distort large extended proteins to โ€˜globulariseโ€™ them. Itโ€™s fine for people that understand those helices are โ€˜bentโ€™ but for non experts itโ€™s confusing. ๐Ÿซค ๐Ÿค” It happens a lot and isnโ€™t well discussed in the community.

Did you know #diatoms are motile? These tiny glass cells have no cilia or flagella and a rigid body yet can glide on surfaces using a specialised slit in the cell wall called the raphe! What is the functional morphology of the raphe? All revealed in our new preprint
