GeneDescription This gene is a member of the cadherin superfamily, genes encoding calcium dependent cell-cell adhesion glycoproteins. The protein encoded by this gene is a large, single-pass transmembrane protein.
GeneFunction Nicolson et al. (1998) reported that mutations in sputnik and mariner affect hair bundle integrity. The genes sputnik, cosmonaut, and orbiter have homozygous viable alleles that cause a recessive adult phenotype. The circling behavior of mutant sputnik adults consists mainly of forward somer-saulting and random lateral looping . Animal homozygous for orbiter rarely survive, but those that do exhibit lateral looping behavior similar to sputnik adults. Thus, sputnik and orbiter adult fish mimic the behavior of fish under micro- or zero-gravity conditions (von Baumgarten et al. 1975) and fish that have undergone lesions or removal of the vestibular organ (Pfeiffer, 1964).Sollner et al. (2004) reported that the defects in sputnik mutants are caused by mutations in cadherin 23 (cdh23). Mutations in Cdh23 also cause deafness and vestibular defects in mice and humans5–9, and the protein is present in hair bundles10,11. They showed that zebrafish Cdh23 protein is concentrated near the tips of hair bundles, and that tip links are absent in homozygous sputniktc317e larvae. Moreover, tip links are absent in larvae carrying weak alleles of cdh23 that affect mechanotransduction but not hair bundle integrity. Finally, they have concluded that conclude that Cdh23 is an essential tip link component required for hair-cell mechanotransduction.
