A tale of two proteins: relationship between HilD & FliZ in SPI1 regulation
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2027-08-01

The Role of Periplasmic Disulfide Bond Status in the Regulation of the Salmonella SPI1 Type Three Secretion System
… is dependent on both the flagellar protein FliZ and the RcsCDB system, which also affects fliZ transcription. Thus, the status of disulfide bonds in the periplasm affects expression of the SPI1 system indirectly via regulation of the flagellar apparatus. RcsCDB can also affect SPI1 …

Phenotypic variation and bistability within flagellar gene network in Salmonella Typhimurium
… which acts as an anti-FlhD4C2factor. Moreover, FliZ-dependent activation of Pclass2 promoters is more pronounced in low nutrient condition and is achieved by repression of the ydiV gene by FliZ. YdiV expression is enhanced in poor media and greatly reduced in rich media. Thus, FliZ and YdiV, in …

Regulation of virulence in Salmonella enterica
… SPI1 regulatory circuit. The flagellar protein FliZ is a Class I regulator of SPI1 that activates hilA expression by affecting HilD protein activity. Thus, FliZ serves as a link between flagellar regulon and SPI1. We provide evidence that the FliZ-dependent regulatory input into SPI1 is limited, …

Switching in bacterial gene expression networks
… from two antagonizing regulatory proteins, FliZ and YdiV. We further demonstrated that the response is bistable: namely, that genetically identical cells can exhibit different phenotypes under identical growth conditions. We further characterized the differences within class 2 and class 3 …

Integration of small RNAs in the control of Salmonella pathogenicity island 1(SPI1)
… downregulation of HilD protein activity through FliZ. In addition to the PhoP-mediated transcriptional repression of hilA expression, PinT acts to efficiently repress hilA expression at the posttranscriptional level through these multiple pathways. This PinT-mediated regulation of SPI1 expression …

Regulation and switching in bacterial gene expression networks in response to nutrients
… loop involving the flagellar regulators RflP and FliZ. This feedback loop governs bimodal expression of class 2 genes. In this work, a second mechanism was found to govern bimodal expression of class 3 genes. In particular, class 3 gene expression is still bimodal even when class 2 gene expression …
