General annotation (Comments)

Function

Effector proteins function to alter host cell physiology and promote bacterial survival in host tissues. This protein includes tyrosine phosphatase and GTPase activating protein (GAP) activities. After bacterial internalization, GAP mediates the reversal of the cytoskeletal changes induced by SopE. This function is independent of its tyrosine phosphatase activity, which remains unclear By similarity.

Catalytic activity

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

Subunit structure

Forms a complex with SicP By similarity.

Subcellular location

Secreted By similarity. Host cytoplasm By similarity. Note: Secreted via type III secretion system 1 (SPI-1 TTSS), and delivered into the host cytoplasm By similarity.

Miscellaneous

Requires SicP as a chaperone for its stability and secretion By similarity.

Sequence similarities

In the N-terminal section; belongs to the YopE family.

Contains 1 tyrosine-protein phosphatase domain.
