Protein
Neuropathy target esterase sws
Gene
sws, CG2212
Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Phospholipase B that deacylates intracellular phosphatidylcholine (PtdCho), generating glycerophosphocholine (GroPtdCho). This deacylation occurs at both sn-2 and sn-1 positions of PtdCho. Its specific chemical modification by certain organophosphorus (OP) compounds leads to distal axonopathy. Plays a role in the signaling mechanism between neurons and glia that regulates glia wrapping during development of the adult brain. Essential for membrane lipid homeostasis and cell survival in both neurons and glia of the adult brain.3 Publications

Catalytic activityi

2-lysophosphatidylcholine + H2O = glycerophosphocholine + a carboxylate.1 Publication
