Predicted to enable actin filament binding activity and ubiquitin protein ligase binding activity. Predicted to act upstream of or within several processes, including auditory receptor cell stereocilium organization; positive regulation of substrate adhesion-dependent cell spreading; and sensory perception of sound. Predicted to be located in cuticular plate; stereocilium base; and stereocilium shaft. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 28. Orthologous to human TRIOBP (TRIO and F-actin binding protein). [provided by Alliance of Genome Resources, Apr 2022]
