Research Abstract

Mouse genetics research has made important contributions to the understanding of the molecular mechanisms of hearing. In this study, we have identified a missense mutation in Myosin VI in Kumamoto shaker/waltzer mouse. The mutation induced partial and incomplete splicing errors. Moreover, by immunofluorescence analysis, MYO6 was disappeared from cuticular plates and was detected the mislocalization in the fused stereocilia bundles. These results suggested possibility with observation of new stereocilia formation mechanism.
