Ulk4 Is Essential for Ciliogenesis and CSF Flow.

ABSTRACT:

Unlabelled

Ciliopathies are an emerging class of devastating disorders with pleiotropic symptoms affecting both the central and peripheral systems and commonly associated with hydrocephalus. Even though ciliary components and three master transcriptional regulators have been identified, little is known about the signaling molecules involved. We previously identified a novel gene, Unc51-like-kinase 4 (ULK4), as a risk factor of neurodevelopmental disorders. Here we took multidisciplinary approaches and uncovered essential roles of Ulk4 in ciliogenesis. We show that Ulk4 is predominantly expressed in the ventricular system, and Ulk4(tm1a/tm1a) ependymal cells display reduced/disorganized cilia with abnormal axonemes. Ulk4(tm1a/tm1a) mice exhibit dysfunctional subcommissural organs, o
