The Ciliopathy Gene Product Cep290 Is Required For Primary Cilium Formation And Microtubule Network Organization, Eli̇f Nur Firat Karalar

Turkish Journal of Biology

The mammalian centrosome/cilium complex is composed of the centrosome, the primary cilium, and the centriolar satellites,which together function in key cellular processes including signaling. Defective assembly, maintenance, and function of the centrosome/cilium complex cause the human genetic diseases known as ciliopathies, which are characterized by a multitude of developmental syndromes including retinal degeneration and kidney cysts. The molecular mechanisms underlying pathogenesis in ciliopathies remain poorly understood, which requires structural and functional characterization of the mutated ciliopathy proteins at the cellular level. To this end, we elucidated the function and regulation of Cep290, which is the most frequently mutated gene in …
