Research Abstract	In this study, a hypothetical phosphate signaling which is predicted from molecular modeling of Erk1-like structure of Otoferlin was explored using cultured cells and OTOF gene deficient mouse. In morphological investigation of spiral ganglion neuron of OTOF gene deficient mouse cochlea, a novel hypoganglionosis like phenotype was detected. The phenotype has a potential for the first morphological model of Auditory Neuropathy.
