Spasmin-like proteins in various ciliates revealed by antibody to purified spasmins of Carchesium polypinum.
It was found that some ciliates, Stentor, Spirostomum and Blepharisma, which can contract rapidly like the stalks of Vorticellidae, have Ca2+-binding proteins that are very similar to spasmins, in the immunological sense. The presence of spasmins in other Protozoa and in some Metazoa was also investigated.
