An extracellular matrix structural constituent. Predicted to be involved in cell-matrix adhesion. Predicted to act upstream of or within sensory perception of sound. Located in extracellular matrix. Is expressed in inner ear. Used to study autosomal dominant nonsyndromic deafness 12. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 12; autosomal recessive nonsyndromic deafness 21; and sensorineural hearing loss. Orthologous to human TECTA (tectorin alpha). [provided by Alliance of Genome Resources, Apr 2022]
