RT "An indispensable role for the MavE effector of Legionella pneumophila in
RT lysosomal evasion.";
RL MBio 12:e03458-e03458(2021).
CC -!- FUNCTION: Virulence effector that is indispensable for endoplasmic
CC reticulum (ER)-mediated remodeling of the Legionella pneumophila-
CC containing vacuole (LCV) and lysosomal evasion (PubMed:33563829).
CC Essential for intracellular replication in human monocyte-derived
CC macrophages (hMDMs) and amoebae, as well as for intrapulmonary
CC proliferation in mice (PubMed:33563829). {ECO:0000269|PubMed:33563829}.
CC -!- SUBUNIT: Homotrimer. {ECO:0000269|PubMed:33563829}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:33563829}. Host
CC vacuole, host pathogen-containing vacuole, host pathogen-containing
CC vacuole membrane {ECO:0000269|PubMed:33563829}; Single-pass membrane
CC protein {ECO:0000255}. Note=Translocated into the host cell via the
CC type IV secretion system (T4SS) (Probable). During infection, localizes
CC to the poles of the LCV membrane (PubMed:33563829).
CC {ECO:0000269|PubMed:33563829, ECO:0000305|PubMed:33563829}.
CC -!- DOMAIN: Contains a C-terminal transmembrane helix, three copies of
CC tyrosine-based sorting motifs, and an NPxY eukaryotic motif, which
CC binds phosphotyrosine-binding domains present on signaling and adapter
CC eukaryotic proteins (PubMed:33563829). The NPxY eukaryotic motif is
CC essential for ER-mediated remodeling and lysosomal evasion by the LCV
CC (PubMed:33563829). {ECO:0000269|PubMed:33563829}.
CC -!- DISRUPTION PHENOTYPE: The null mutant fails to remodel the LCV with
CC endoplasmic reticulum (ER)-derived vesicles and is trafficked to the
CC lysosomes where it is degraded (PubMed:33563829). Mutant is defective
CC for intracellular growth in hMDMs, amoeba and for intrapulmonary
CC proliferation in mice (PubMed:33563829). {ECO:0000269|PubMed:33563829}.
