== Function ==
[[Category: Jiang, Y L.]]
[https://www.uniprot.org/uniprot/NTCA_NOSS1 NTCA_NOSS1] Required for full expression of proteins subject to ammonium repression. Transcriptional activator of genes subject to nitrogen control.  Has affinity for the xisA upstream region. Binds to a 66 bp region containing three repeats of the consensus recognition sequence 5'-ACATT-3'.
