CC   -!- FUNCTION: Effector proteins function to alter host cell physiology and
CC       promote bacterial survival in host tissues. This protease targets the
CC       host cell ubiquitin pathway by acting as a deubiquitinase in infected
CC       host cells (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}. Host cytoplasm
CC       {ECO:0000250}. Note=Secreted via type III secretion system 2 (SPI-2
CC       TTSS), and delivered into the host cytoplasm. In phagocytic cells
CC       localizes to the Salmonella-containing vacuole (SCV). In epithelial
CC       cells localizes to the Salmonella-containing vacuole (SCV) and to the
CC       Salmonella-induced filaments (Sifs), which are tubular membrane
CC       extensions from the SCV that are formed at late stages of infection (By
CC       similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the peptidase C79 family. {ECO:0000305}.
