Effector proteins function to alter host cell physiology and promote bacterial survival in host tissues. This protein is an E3 ubiquitin ligase that interferes with host's ubiquitination pathway and modulates the acute inflammatory responses, thus facilitating bacterial colonization within the host cell. IpaH9.8 Protein, Shigella flexneri, Recombinant (His) is expressed in yeast with N-6xHis tag. The predicted molecular weight is 64.0 kDa and the accession number is D2AJU0.
