  • 功能：
    Member of the two-component regulatory system PhoP/PhoQ involved in adaptation to low Mg(2+) environments and the control of acid resistance genes. In low periplasmic Mg(2+), PhoQ phosphorylates PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP-repressed genes (PRG). In high periplasmic Mg(2+), PhoQ dephosphorylates phospho-PhoP, resulting in the repression of PAG and may lead to expression of some PRG. Mediates magnesium influx to the cytosol by activation of MgtA. Promotes expression of the two-component regulatory system rstA/rstB and transcription of the hemL, mgrB, nagA, slyB, vboR and yrbL genes.
  • 基因功能参考文献：
    1. findings directly link the PhoQ/PhoP two-component system to bacterial osmosensing PMID: 29183977
    2. Both MicA and GcvB bind phoPQ mRNA in vivo and in vitro around the translation initiation region of phoP. Binding of either small RNA is sufficient to inhibit ribosome binding and induce mRNA degradation PMID: 23300478
    3. Taken together, these results demonstrate that a decrease in the oxidizing activity of the periplasm stimulates PhoQ/PhoP and may reveal a new input stimulus for this important two-component system. PMID: 22267510
    4. MicA directly pairs with phoPQ mRNA in the translation initiation region of phoP and presumably inhibits translation by competing with ribosome binding. PMID: 20345657
