Fused has evolved divergent roles in vertebrate Hedgehog signalling and motile ciliogenesis.

ABSTRACT: Hedgehog (Hh) signalling is essential for several aspects of embryogenesis. In Drosophila, Hh transduction is mediated by a cytoplasmic signalling complex that includes the putative serine-threonine kinase Fused (Fu) and the kinesin Costal 2 (Cos2, also known as Cos), yet Fu does not have a conserved role in Hh signalling in mammals. Mouse Fu (also known as Stk36) mutants are viable and seem to respond normally to Hh signalling. Here we show that mouse Fu is essential for construction of the central pair apparatus of motile, 9+2 cilia and offers a new model of human primary ciliary dyskinesia. We found that mouse Fu physically interacts with Kif27, a mammalian Cos2 orthologue, and linked Fu to known structural components of the central pair apparatus, providing evidence for the first regul
