Predicted to enable several functions, including profilin binding activity; small GTPase binding activity; and transmembrane transporter binding activity. Involved in positive regulation of cell migration. Predicted to be located in several cellular components, including brush border; mitotic spindle; and ruffle membrane. Predicted to colocalize with spindle microtubule. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 1 and sensorineural hearing loss. Orthologous to human DIAPH1 (diaphanous related formin 1). [provided by Alliance of Genome Resources, Apr 2022]
