  • Reporter gene assays were used to validate promoter activity.
  • Copper concentration was manipulated to test inducibility and repressibility.

    • Main Results:

    • A novel promoter responsive to copper was identified in Tetrahymena thermophila.
    • The promoter demonstrated robust activity upon copper induction.
    • Gene expression was effectively repressed in the absence of copper.

    Conclusions:

    • A copper-inducible and repressible promoter has been successfully identified in Tetrahymena thermophila.
    • This promoter provides a valuable tool for controlled gene expression in this ciliate.
    • Tetrahymena thermophila shows significant promise as a versatile platform for heterologous protein production in biotechnology.
