This family consists of several eukaryotic paraflagellar rod component proteins. The eukaryotic flagellum represents one of the most complex macromolecular structures found in any organism and contains more than 250 proteins [1]. In addition to its locomotive role, the flagellum is probably involved in nutrient uptake since receptors for host low-density lipoproteins are localised on the flagellar membrane as well as on the flagellar pocket membrane [2].
