MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a B9 domain protein, which are exclusively found in ciliated organisms. The gene is upregulated during mucociliary differentiation, and the encoded protein localizes to basal bodies and cilia. Disrupting expression of this gene results in ciliogenesis defects. [provided by RefSeq, Oct 2009]
PHENOTYPE: Mice carrying a targeted mutation of this gene exhibit preweaning lethality, hydrops fetalis, and abnormalities in craniofacial, limb, and eye development. [provided by MGI curators]
