Type III secretion system effector YopR (IPR013349)

Short name: T3SS_YopR

Overlapping homologous superfamilies


Family relationships



Proteins in this entry are type III secretion system effectors, named differently in different species and designated YopR in Yersinia. Yersinia employs a type III secretion system (T3SS) to secrete and translocate virulence factors into to the cytoplasm of mammalian host cells. One of the secreted virulence factors is YopR (Yersinia outer protein R), encoded by the YscH (Yersinia secretion H) gene. This Yop protein is unusual in that it is released to the extracellular environment rather than injected directly into the target cell as are most Yop proteins [PMID: 10209737, PMID: 8709853].
