Predicted to be involved in sensory perception of sound. Predicted to act upstream of or within auditory receptor cell stereocilium organization and protein localization to organelle. Predicted to be active in microvillus; stereocilium base; and stereocilium shaft. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 101. Orthologous to human GRXCR2 (glutaredoxin and cysteine rich domain containing 2). [provided by Alliance of Genome Resources, Apr 2022]
