CC -!- FUNCTION: Inhibits nitric oxide (NO) production in activated
CC macrophages. Acts by inhibiting expression of the host inducible nitric
CC oxide synthase (iNOS). PPE2 is translocated into the host macrophage
CC nucleus, where it interacts with a GATA-binding site overlapping with
CC the TATA box of NOS2 (iNOS) promoter, and strongly inhibits NOS2 gene
CC transcription. Reduction in NO production in turn facilitates
CC intracellular survival of the bacilli inside the macrophage. In
CC addition, disrupts the assembly of NADPH oxidase complex, which
CC inhibits NADPH oxidase-mediated reactive oxygen species (ROS)
CC generation in macrophages and favors M.tuberculosis survival. Acts by
CC interacting with NCF2, the cytosolic subunit of NADPH oxidase, and
CC preventing translocation of NCF2 and NCF1 to the membrane, which causes
CC a reduction of the functional assembly of NADPH oxidase complex and a
CC decrease in NADPH oxidase activity. {ECO:0000250|UniProtKB:P9WI47}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P9WI47}. Host
CC cytoplasm {ECO:0000250|UniProtKB:P9WI47}. Host nucleus
CC {ECO:0000250|UniProtKB:P9WI47}.
CC -!- DOMAIN: Contains a conserved PPE N-terminal domain and a variable C-
CC terminal domain. The C-terminal region includes a SH3-like region, a
CC leucine zipper DNA-binding motif and a functional nuclear localization
CC signal (NLS). {ECO:0000250|UniProtKB:P9WI47}.
CC -!- SIMILARITY: Belongs to the mycobacterial PPE family. {ECO:0000305}.
