Temporal and spatial organisation of microtubules is determined by microtubule organising centers and a number of appendages and accessory proteins. Members of the SSNA1\/DIP13 family are coiled coil proteins that are known to localise to microtubular structures like centrosomes and flagella, but are otherwise poorly characterised. We have identified a homologue of SSNA1\/DIP13 in the parasitic protist <jats:italic>Toxoplasma gondii<\/jats:italic> and found it localises to parasite-specific cytoskeletal structures: the conoid in the apical complex of mature and dividing cells and the basal complex in elongating daughter cells during cell division. This protein is dispensable for parasite growth <jats:italic>in vitro<\/jats:italic>. However, quite remarkably, this coiled coil protein is able to self-associate into higher order structures both <jats:italic>in vitro<\/jats:italic> and <jats:italic>in vivo<\/jats:italic> and its overexpression is impairing parasite division.<\/jats:p>","DOI":"10.1038\/srep27809","type":"journal-article","created":{"date-parts":[[2016,6,21]],"date-time":"2016-06-21T09:29:03Z","timestamp":1466501343000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["An evolutionarily conserved SSNA1\/DIP13 homologue is a component of both basal and apical complexes of Toxoplasma gondii"],"prefix":"10.1038","volume":"6","author":[{"given":"Maude F.","family":"L\u00e9v\u00eaque","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurence","family":"Berry","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9bastien","family":"Besteiro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2016,6,21]]},"reference":[{"key":"BFsrep27809_CR1","doi-asserted-by":"publisher","first-page":"161","DOI":"10.1038\/nrm2100","volume":"8","author":"J L\u00fcders","year":"2007","unstructured":"L\u00fcders, J. & Stearns, T.
