XLNR — Aspergillus nidulans FGSC A4

Summary

ANIA_07610 (XLNR, AnXLNR) on Aspergillus nidulans chromosome 4 encodes a Zn2Cys6 DNA-binding transcription factor with RNA polymerase II-specific activity. The product belongs to the XlnR/Xlr1 family. AnXLNR is associated with the positive regulation of xylan and cellulose breakdown, as well as pentose, galactose, and polysaccharide breakdown. It is linked to carbon catabolite repression, the glucose effect, fermentation, secretion, and digestion. The protein localises to the nucleus and is connected to the regulation of gene expression and transcription by RNA polymerase II. Studies of related genes in other species link the family to similar regulatory roles in plant cell wall degradation.
