This entry includes a group of cilia- and flagella-associated protein, including Kur from zebrafish and C21orf59 from humans. Kur has been shown to play a dual role in cilia motility and polarization [].Primary ciliary dyskinesia (PCD) is caused when defects of motile cilia lead to chronic airway infections, male infertility, and situs abnormalities. Mutations in the C21orf59 gene cause ciliary dyskinesia, primary, 26 (CILD26) [].
