The proteome of the mouse photoreceptor sensory cilium complex.

ABSTRACT: Primary cilia play critical roles in many aspects of biology. Specialized versions of primary cilia are involved in many aspects of sensation. The single photoreceptor sensory cilium (PSC) or outer segment elaborated by each rod and cone photoreceptor cell of the retina is a classic example. Mutations in genes that encode cilia components are common causes of disease, including retinal degenerations. The protein components of mammalian primary and sensory cilia have not been defined previously. Here we report a detailed proteomics analysis of the mouse PSC complex. The PSC complex comprises the outer segment and its cytoskeleton, including the axoneme, basal body, and ciliary rootlet, which extends into the inner segment of photoreceptor cells. The PSC complex proteome contains 1968 protei
