Giant #proteins in a giant cell: Molecular basis of ultrafast Ca2+-dependent cell contraction https://www.science.org/doi/10.1126/sciadv.add6550

"#Spirostomum, is a genus of millimeter-scale #SingleCelled #protists that are known for their incredibly rapid movement. They are capable of some of the fastest movement in the biological world due to their ultrafast contraction."

Giant proteins in a giant cell: Molecular basis behind fastest biological movement in single-celled eukaryotes

In his famous letter to the Royal Society dated Oct. 9, 1676, Antonie van Leeuwenhoek described a single-celled eukaryote (Vorticella) and its fascinating ultrafast cell contraction. This kind of ultrafast cell contraction triggered by a Ca2+-dependent mechanism is distinct from the adenosine triphosphate (ATP)-dependent mechanisms found in actin-myosin and dynein/kinesin-tubulin systems.
