nirA — Aspergillus nidulans FGSC A4

Summary

ANIA_02324 (nirA) on Aspergillus nidulans FGSC A4 chromosome 7 encodes a Zn(II)2Cys6 transcription factor with DNA-binding and RNA polymerase II-specific regulatory activity. The gene is associated with nitrate assimilation and its regulation, including nitrate import, nitrite response, and nitrogen utilization. It is also linked to nitric oxide metabolism, appressorium formation, hyphal growth, sexual reproduction, and nuclear import/export processes. Additional associations include the pentose-phosphate shunt, DNA replication, and methylation. The encoded protein localizes to both the cytosol and nucleus.
