MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a non-collagenous glycoprotein component of the tectorial membrane, which covers the auditory hair cells in the cochlea of the inner ear. A similar protein in mouse functions in low-frequency hearing. [provided by RefSeq, Jul 2013]
PHENOTYPE: Homozygotes for a null allele show an enlarged tectorial membrane with a disrupted striated-sheet matrix, absence of the marginal band, and low-frequency hearing loss. However, basilar-membrane and neural tuning are both enhanced in high-frequency cochlear regions, with little loss in sensitivity. [provided by MGI curators]
