Predicted to enable glutathione oxidoreductase activity. Predicted to be involved in inner ear receptor cell stereocilium organization and vestibular receptor cell development. Predicted to act upstream of or within inner ear auditory receptor cell differentiation; post-embryonic animal organ morphogenesis; and sensory perception of sound. Predicted to be active in kinocilium and stereocilium. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 25. Orthologous to human GRXCR1 (glutaredoxin and cysteine rich domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
