Function
Virulence regulator that has both architectural and regulatory roles. Impacts cell wall functions and pathogenesis through regulation of multiple genes, including the espACD operon, which is a key ESX-1 component. Influences target gene expression positively or negatively, depending on its binding position relative to the genes it controls. Acts by binding directly to the DNA. May play a central role in regulating virulence gene expression. {ECO:0000269|PubMed:18685700, ECO:0000269|PubMed:21883526, ECO:0000269|PubMed:22389481, ECO:0000269|PubMed:22479184, ECO:0000269|PubMed:23743602}.
