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

Espinosa Javier, Rodríguez-Mateos Francisco, Salinas Paloma, Lanza Val F, Dixon Ray, de la Cruz Fernando, Contreras Asuncion

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...
