  • 功能：
    Key calcium ion sensor involved in the Ca(2+)-triggered synaptic vesicle-plasma membrane fusion and in the control of neurotransmitter release at these output synapses. Interacts in a calcium-dependent manner to the presynaptic SNARE proteins at ribbon synapses of cochlear inner hair cells (IHCs) to trigger exocytosis of neurotransmitter. Also essential to synaptic exocytosis in immature outer hair cells (OHCs). May also play a role within the recycling of endosomes.

    1. two mutations-c.5098G > C (p.Glu1700Gln) and c.1702C > T (p.Arg568Trp)-in the OTOF gene were found to be correlated with ANSD. PMID: 30368385
    2. ConclusionOur findings implicate OTOF as a potential major contributor to hearing loss in the Saudi population, while highlighting the low contribution of GJB2, thus offering important considerations for clinical testing strategies for Saudi patients. PMID: 29048421
    3. This study suggested considerable genetic heterogeneity in the causation of hearing loss in Dhadkai. Recessive mutations were observed in at least three genes causing hearing loss: OTOF (p.R708X), SLC26A4 (p.Y556X) and CLDN14 (p.V85D). Mutation p.R708X appeared to be the major cause of hearing impairment in Dhadkai. PMID: 29434063
    4. Although both otoferlin and synaptotagmin bind membrane fusion SNARE proteins, only otoferlin interacts with the L-type calcium channel Cav1.3. PMID: 28696301
    5. three unrelated 2 to 6 year-old children who were diagnosed as auditory neuropathy patients who complained of severe hearing loss when they had fever had otoferlin (OTOF) homozygous or compound heterozygous mutations with the genotypes c.2975_2978delAG/c.4819C>T, c.4819C>T/c.4819C>T, or c.2382_2383delC/c.1621G>A PMID: 26778470
    6. The s conclude that the TRC40 pathway is critical for hearing and propose that otoferlin is an essential substrate of this pathway in hair cells. PMID: 27458190
    7. In Otof(I515T/I515T) inner hair cells (IHCs), otoferlin levels are diminished by 65%, synaptic vesicles are enlarged, and exocytosis during prolonged stimulation is strongly reduced indicating that otoferlin is critical for the reformation of properly sized and fusion-competent synaptic vesicles.

    8. Our results confirmed that mutations in OTOF gene were a major cause of congenital Auditory neuropathy spectrum disorder (ANSD) in China. Identification of OTOF mutations can facilitate diagnosis, clinical intervention and counseling for congenital ANSD PMID: 26818607

    10. Two mutations in the otoferlin gene, nonsense mutation p.R425X, contributes to a premature stop codon, may result in a truncated polypeptide, which strongly suggests its pathogenicity for auditory neuropathy spectrum disorder. The missense mutation p.L1665P results in a single amino acid substitution in a highly conserved region. PMID: 28335750

    28. mechano-electrical transduction and cochlear amplification are normal in patients with OTOF mutations. Potentials are consistent with decreased neurotransmitter release resulting in abnormal dendritic activation and impairment of auditory nerve firing. PMID: 19636622
