The putative cellodextrin transporter-like protein CLP1 is involved in cellulase induction in Neurospora crassa

ABSTRACT: Neurospora crassa recently has become a novel system to investigate cellulase induction. Here, we discovered a novel membrane protein, CLP1 (NCU05853), a putative cellodextrin transporter-like protein, that is a critical component of the cellulase induction pathway in N. crassa. Although CLP1 protein cannot transport cellodextrin, the suppression of cellulase induction by this protein was discovered on both cellobiose and Avicel. The co-disruption of the cellodextrin transporters cdt2 and clp1 in strain M-NM-^T3M-NM-2G formed strain CPL7. With induction by cellobiose, cellulase production was enhanced 6.9-fold in CPL7 compared with M-NM-^T3M-NM-2G. We also showed that the suppression of cellulase expression by CLP1 occurred by repressing the expression of cellodextrin transporters, particu
