Predicted to enable actin binding activity. Predicted to be involved in positive regulation of DNA-binding transcription factor activity; positive regulation of Rho protein signal transduction; and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within positive regulation of transcription, DNA-templated and protein import into nucleus. Located in sarcomere. Orthologous to human ABRA (actin binding Rho activating protein). [provided by Alliance of Genome Resources, Apr 2022]
