Disease relevance of ipgC

Characterization of invasion plasmid antigen genes (ipaBCD) from Shigella flexneri [1].
Detection of virulent Shigella and enteroinvasive Escherichia coli by induction of the 43 kDa invasion plasmid antigen, ipaC [2].

High impact information on ipgC

Invasion plasmid antigen C (IpaC) has been identified as the primary effector protein for Shigella invasion of epithelial cells [3].
Nucleotide sequence of invasion plasmid antigen gene ipaA from Shigella flexneri 5 [4].
Plasmids expressing His6-IpgC either alone or together with IpaB or IpaC under the control of an IPTG-inducible lac promoter were introduced into ipgC, ipaB or ipaC mutants [5].
The first region was cloned into an E. coli HB101 strain containing noninvasive Tn1 insertion mutants of the form I plasmid, and expression of ipa (invasion plasmid antigen) gene products was restored [6].
Recombinant plasmids carrying this regulatory gene, designated ipaR, were found to restore full virulence to a non-invasive ipaR::Tn5 insertion mutant [M90T-W(pHS1042)] that had lost the ability to synthesize four Ipa antigens (IpaA, 70 kDa; IpaB, 62 kDa; IpaC, 42 kDa; and IpaD, 37 kDa) [7].

Chemical compound and disease context of ipgC

The invasion plasmid antigen, ipaC (43 kDa) of Shigella spp. and enteroinvasive Escherichia coli (EIEC) could be induced in vitro by growing them in the presence of Congo red [2].

Biological context of ipgC

Of four invasion plasmid antigen proteins (IpaA,B,C and D), IpaC plays an important role in the pathogenicity of this pathogen [8].
Antibody response of monkeys to invasion plasmid antigen D after infection with Shigella spp [9].

Analytical, diagnostic and therapeutic context of ipgC

Molecular cloning of invasion plasmid antigen (ipa) genes from Shigella flexneri: analysis of ipa gene products and genetic mapping [10].
