Predicted to enable RNA binding activity; identical protein binding activity; and transcription termination site sequence-specific DNA binding activity. Acts upstream of or within circadian rhythm and termination of RNA polymerase II transcription. Predicted to be located in several cellular components, including growth cone; intercellular bridge; and nuclear lumen. Predicted to be active in nuclear body. Human ortholog(s) of this gene implicated in amyotrophic lateral sclerosis type 4 and ataxia with oculomotor apraxia type 2. Orthologous to human SETX (senataxin).
