It is not surprising that VtrA and VtrB are regulons, because both Vp-ToxR and Hfq are global regulators and their regulons comprise many genes, including virulence-associated genes ❋ Toshio Kodama Et Al. (2010)
Little is known about how these varied parasites regulate their transcriptional regulons. ❋ Unknown (2010)
Although a consensus sequence recognized by VtrB is unknown, it is possible that this characteristic of low G+C content in Vp-PAI might be one of the factors deciding the specificity of VtrB regulons. ❋ Toshio Kodama Et Al. (2010)
This observation suggests the existence of regulons whose regulation is conserved across this ancient phylum. ❋ Unknown (2010)
Genome-wide transcript analysis of the VtrA and VtrB regulons is shown. ❋ Toshio Kodama Et Al. (2010)
Even though transcription factors are underrepresented in apicomplexans, the distribution of these factors and their associated regulons reflect common and family-specific transcriptional regulatory processes. ❋ Unknown (2010)
The N-terminal domain of ToxR encodes a WHTH DNA-binding domain, which is a typical characteristic of the OmpR family of proteins and is necessary for transcriptional regulation of ToxR regulons ❋ Toshio Kodama Et Al. (2010)
These studies provided strong evidence for the presence of a highly organized post-transcriptional regulatory system that coordinates the fates of functionally related groups of mRNAs as 'post-transcriptional operons' or RNA regulons ❋ Unknown (2008)
Mutation of sarA does result in reduced expression of the ica operon and consequently reduced production of the polysaccharide intercellular adhesion (PIA), but our direct comparison of sarA and ica mutants generated in the same strain used in the experiments reported here (UAMS-1) demonstrate that this cannot account for the biofilm defect in a sarA in biofilm formation, we compared the regulons defined by growth within a biofilm and by mutation of sarA. ❋ Unknown (2008)
First, TFs with small regulons correspond to a class of FFLs caused by the hierarchical regulation of groups of operons, mostly associated to catabolite repression. ❋ Francisco M. Camas Et Al. (2008)
Finally, our previous studies characterizing the sarA and biofilm regulons in UAMS-1 ❋ Unknown (2008)

Fig. 6 and Table 1), it is possible that they are more directly related to the control of pathogenicity than Vp-ToxR and Hfq. vtrA or vtrB deletion strains revealed that VtrA and VtrB regulons were specifically encoded in the Vp-PAI region ( ❋ Toshio Kodama Et Al. (2010)
