hilA transcriptional regulator

hilA, together with hilC and hilD, are global regulators and control the expression of the Salmonella pathogenicity island I(SPI-1) genes in S. typhimurium on which the SPI-1 T3SS injectisome is encoded 1. Over 25 genes that are needed for host invasion are located on the SPI-1 2. Also, hilA activates SPI-1 operon mediated by the prg and inv promoters 3,4. hilA controls SPI genes in response to enviromental needs like pH and oxygen levels4–6.
