    Summary
    Predicted to enable Hsp90 protein binding activity and telomeric DNA binding activity. Involved in several processes, including DNA damage checkpoint signaling; determination of adult lifespan; and response to X-ray. Located in cytoplasm. Is expressed in several structures, including gonad and head ganglion. Orthologous to human TELO2 (telomere maintenance 2). [provided by Alliance of Genome Resources, Dec 2024]
