Predicted to enable actin binding activity. Predicted to contribute to guanyl-nucleotide exchange factor activity. Predicted to be involved in several processes, including Rho protein signal transduction; positive regulation of ruffle assembly; and sensory perception of sound. Predicted to be located in cytosol and stereocilium tip. Predicted to be part of protein-containing complex. Predicted to be active in ruffle membrane. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 106. Orthologous to human EPS8L2 (EPS8 like 2). [provided by Alliance of Genome Resources, Apr 2022]
