xlnR — Aspergillus nidulans FGSC A4

Summary

ANIA_09458, symbol xlnR, on chromosome 6 of Aspergillus nidulans FGSC A4, encodes a xylanase regulator with a Zn2Cys6 DNA-binding domain and DNA-binding transcription factor activity specific to RNA polymerase II. The gene is associated with the positive regulation of xylan and cellulose breakdown, as well as pentose, galactose, and polysaccharide breakdown. It is also linked to carbon catabolite repression, the glucose effect, fermentation, secretion, and digestion. Localisation evidence places the product in the nucleus. Related genes in other species, including Fusarium oxysporum and Verticillium dahliae, are linked to the XlnR family, though this is not established for the A. nidulans gene itself.
