Disease relevance of hilC

• A mutation in hilD significantly reduces the ability of S. typhimurium to enter tissue culture cells, whereas a mutation in hilC only modestly affects Salmonella invasion [1].

High impact information on hilC

• Rather, we show that 'SPI1 inducing conditions' cause independent activation of the rtsA, hilC and hilD genes in the absence of known regulators [2].
• The two-component regulatory systems, SirA/BarA and OmpR/EnvZ, function through HilD, thus inducing hilC, rtsA and hilA [2].
• The hilA and hilC promoters contain multiple binding sites of each type, whereas the hilD promoter contains a site that binds HilC but not HilD without additional binding elements [3].

Biological context of hilC

• RtsA also induces expression of hilD, hilC, and the invF operon [4].

Other interactions of hilC

• Gel electrophoretic shift and DNase footprinting assays revealed that purified HilC and HilD proteins can bind to multiple regions in the hilA and hilC promoters and to a single region in the hilD promoter [3].
• The HilC and HilD proteins had no major effect on transcription from the hilA or hilD promoters using purified proteins in vitro but changed the choice of promoter at hilC [3].
