Otoancorin is a protein found in the vertebrate inner ear, on the sensory epithelia where it connects to the gel matrix.[5]

Otoancorin is found in the cochlea, utricule, saccule, and under the cupulae on the surface of apical dells in the sensory epithelia.[6]

In humans the gene that encodes otoancorin is called OTOA. It is on chromosome 16p12.2 and contains 28 exons. A recessive mutation in this gene called IVS12+2T>C results in deafness. The human protein has 1,153 amino acids.[6]

In the mouse, this protein has 1088 amino acids.[6] In mice otoancorin is needed to attach the tectorial membrane to the inner hair cells in the cochlea.[7]
