RT "A glutamate-dependent redox system in blood cells is integral for
RT phagocytosis in Drosophila melanogaster.";
RL Curr. Biol. 23:2319-2324(2013).
CC -!- FUNCTION: Probable glutamate transporter which transports extracellular
CC glutamate into the cells. Regulates the production of intracellular
CC reactive oxygen species (ROS) probably by controlling the synthesis of
CC antioxidant glutathione. By regulating ROS production in blood cells,
CC required for maintaining bacteria phagocytosis following infection with
CC S.aureus and possibly E.coli. {ECO:0000269|PubMed:24210616}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:24210616};
CC Multi-pass membrane protein {ECO:0000255}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=A {ECO:0000312|FlyBase:FBgn0033572};
CC IsoId=Q4V5R4-1; Sequence=Displayed;
CC Name=C {ECO:0000312|FlyBase:FBgn0033572};
CC IsoId=Q4V5R4-2; Sequence=VSP_058852, VSP_058853;
CC -!- DEVELOPMENTAL STAGE: Expressed in the hemolymph of larvae and adults.
CC {ECO:0000269|PubMed:24210616}.
CC -!- DISRUPTION PHENOTYPE: RNAi-mediated knockdown in adult blood cells
CC results in decreased survival following infection with S.aureus. Adults
CC infected with S.aureus display decreased phagocytosis, increased
CC bacterial load and increased production of reactive oxygen species
CC (ROS) in the hemolymph. Phagocytosis of latex beads is normal, however
CC flies pre-injected with S.aureus display a significant decrease in
CC subsequent bead phagocytosis. Increased survival following infection
CC with L.monocytogenes. Increased extracellular glutamate in the
CC hemolymph. No effect on motor functions, adult weight and no increase
CC in susceptibility to wounding. Induction of the antimicrobial peptides
CC Drs and DptA in response to S.aureus or E.coli infection is not
CC affected. {ECO:0000269|PubMed:24210616}.
CC -!- MISCELLANEOUS: The name 'polyphemus' derives from the Cyclops in Greek
CC mythology that failed to guard against Odysseus as mutants are unable
CC to defend against microbial infection. {ECO:0000303|PubMed:24210616}.
CC -!- SIMILARITY: Belongs to the amino acid/polyamine transporter 2 family.
CC {ECO:0000305}.
