Septins regulate cytokinesis and multicellular development in the closest living relatives of animals
ABSTRACT Septins are cytoskeletal proteins that regulate cytokinesis in fungi and animals, yet their functions in choanoflagellates — the closest living relatives of animals — have remained unknown. Salpingoeca rosetta, a choanoflagellate that switches between unicellular and multicellular forms, encodes four septins c...
