| Research Abstract |
To identify mutations that affect the photoreceptor development and maintenance, we performed early pressure screen using a GFP transgenic line of zebrafish. We showed four mutations which affect ciliary development in photoreceptors. We found that these mutations affect in the ciliogenesis of other sensory neurons including olfactory cells in the nasal pit and hair cells in the inner ear. We also showed that male germ cell-associated kinase, Mak, regulates retinal photoreceptor ciliary length and subcompartmentalization. Our results suggest that Mak is essential for ciliary protein transport, regulation of ciliary length, and is required for the long-term survival of photoreceptors.
