We used a mass spectrometry-based approach to characterize the proteome of the mechanosensory
hair bundle of auditory and vestibular receptor cells, followed by characterization of novel deafness
candidate genes. The impact of this approach on hearing research is several fold:
- Identification of novel deafness genes: The proteomics-based approach lead to the identification
of 4 novel deafness genes so far (BCK, CLIC5, FSCN2, XIRP2)
- Molecular characterization of the hair bundle: the comprehensive characterization of the hair
bundle proteome provides a crucial compendium for a deeper understanding of processes
facilitating and integral to hair cell mechanotransduction
- To demonstrate in vivo relevance of the candidate genes, the CRISPR/Cas9 technology was
used to generate mouse models. Francis et al. (2015) is the first paper using the CRISPR
technology in hearing research
