CC   -!- FUNCTION: Secreted tyrosine phosphatase that plays a critical role
CC       during infection as a bacterial effector protein that counteracts host
CC       defenses. Required for intramacrophage survival.
CC       {ECO:0000250|UniProtKB:A0A0H3K9F2}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] +
CC         phosphate; Xref=Rhea:RHEA:10684, Rhea:RHEA-COMP:10136, Rhea:RHEA-

CC         ChEBI:CHEBI:82620; EC=3.1.3.48;
CC         Evidence={ECO:0000250|UniProtKB:A0A0H3K9F2};
CC   -!- SUBUNIT: Interacts with host CORO1A.
CC       {ECO:0000250|UniProtKB:A0A0H3K9F2}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:A0A0H3K9F2}.
CC       Note=Secreted intracellularly upon bacterial infection of macrophages.
CC       {ECO:0000250|UniProtKB:A0A0H3K9F2}.
CC   -!- PTM: Phosophorylations at Tyr-122 and Tyr-123 are essential for
CC       phosphatase activity. {ECO:0000250|UniProtKB:A0A0H3K9F2}.
CC   -!- SIMILARITY: Belongs to the low molecular weight phosphotyrosine protein
CC       phosphatase family. {ECO:0000305}.
