PipX, the coactivator of NtcA, is a global regulator in cyanobacteria.

Proceedings of the National Academy of Sciences of the United States of America - 10 Jun 2014

Abstract excerpt

To modulate the expression of genes involved in nitrogen assimilation, the cyanobacterial PII-interacting protein X (PipX) interacts with the global transcriptional regulator NtcA and the signal transduction protein PII, a protein found in all three domains of life as an integrator of signals of the nitrogen and carbon balance. PipX can form alternate complexes with NtcA and PII, and these interactions are...
