TranscriptomicsTranscription profiling by array of adenylylation of mycobacterial Glnk (PII) protein induced by nitrogen limitation
PII proteins are pivotal regulators of nitrogen metabolism in most prokaryotes, controlling the activities of many targets, including nitrogen assimilation enzymes, two component regulatory systems and ammonium transport proteins. Escherichia coli contains two PII-like proteins, PII (product of glnB...

ProteomicsThe signal transduction protein PII controls ammonium, nitrate and urea uptake in cyanobacteria
PII signal transduction proteins are widely spread among all domains of life where they regulate a multitude of carbon and nitrogen metabolism related processes. Non-diazotrophic cyanobacteria can utilize a high variety of organic and inorganic nitrogen sources. In recent years, several physiologica...

TranscriptomicsTranscription profiling of Arabidopsis wild type and PII deficient plants grown on different nitrogen sources
In E.Coli, PII protein is known to be a sensor of medium nitrogen status and to regulate some nitrogen metabolism steps (e.g.glutamin synthase and ammonium transporter regulations). Arabidopsis PII protein is the only homolog gene found in the arabidopsis genome and its role is still unclear. The go...

ProteomicsThe PII protein-protein interaction network in Azospirillum brasilense reveals a novel role of PII in the control of c-di-GMP homeostasis
The PII family comprises a group of widely distributed signal transduction proteins ubiquitous present in prokaryotes and in the chloroplast of plants. The PII proteins sense the levels of key metabolites ATP, ADP and 2-oxoglutarate which affect the PII structure and the ability of PII to interact w...

TranscriptomicsExpression data from MCF7 cell line after silencing of Estrogen receptor
We propose the hypothesis that loss of estrogen receptor function which leads to endocrine resistance in breast cancer, also results in de-differentiation from an epithelial to a mesenchymal phenotype that is responsible for increased aggressiveness and metastatic propensity. siRNA mediated silencin...

ProteomicsPII interactions with the acetyl-CoA carboxylase subunits BADC and BCCP co-regulate lipid and nitrogen metabolism in Arabidopsis
In plants the initiation of fatty acid synthesis is catalyzed by acetyl-CoA carboxylase (ACCase) which produces malonyl-CoA. The heteromeric form of ACCase (htACCase) is a holoenzyme consisting of biotin carboxylase and carboxyltransferase sub-complexes, both of which are subject to extensive regula...

ProteomicsThe Novel PII-Interacting Regulator PirC (Sll0944) Identifies 3-Phosphoglycerate Mutase (PGAM) as Central Control Point of Carbon Storage Metabolism in Cyanobacteria
Nitrogen limitation imposes a major transition in the life-style of non-diazotrophic cyanobacteria, which is regulated via a complex interplay of regulatory factors, involving, the nitrogen-specific transcription factor NtcA and the pervasive signal processor PII. Immediately upon nitrogen-limitatio...
