The novel repressor Rce2 competes with Ace3 to regulate cellulase gene expression in the filamentous fungus Trichoderma reesei

The filamentous fungus Trichoderma reesei is widely used for industrial cellulase production. In T. reesei , cellulase gene expression is tightly controlled by a regulatory network involving multiple transcription factors. Here, we isolated a novel protein, Rce2, using a pull‐down assay and mass spectrometry analysis, from a partial carbon catabolite de‐repression mutant, T. reesei Rut‐C30, cultured under glucose‐repressing conditions.
