Abnormalities in cilia result in various ciliopathies, including polycystic kidney disease (PKD), Bardet-Biedl syndrome (BBS), and oral-facial-digital syndrome type I (OFD1), which show genetic defects associated with cilia formation. Although an increasing number of human diseases is attributed to ciliary defects, the functions or regulatory mechanisms of several ciliopathy genes remain unclear. Because cilia are deep in vivo, studying ciliogenesis is challenging. Here, we demonstrate that IK is essential for ciliogenesis in vivo. Results In the absence of IK, zebrafish embryos showed various ciliopathy phenotypes, such as body curvature, abnormal otoliths, and cyst formation in the kidney. RNA sequencing analysis showed that IK positively regulated ofd1 expression required for cilium assembly. Downregulation of ofd1 expression upon depletion of IK led to ciliary defects that was rescued by restoration of ofd1 expression. Interestingly, IK affected ciliogenesis particularly in the proximal tubule but not in the distal tubule in the kidney. Conclusions This study demonstrates the role of IK in ciliogenesis in vivo for the first time. Loss of IK in zebrafish embryos displays various ciliopathy phenotypes with abnormal ciliary morphology in ciliary tissues. Our findings on the IK–OFD1 axis provide new insights into the biological function of IK in clinical ciliopathy studies in humans.
