CC -!- FUNCTION: Hydrolase that metabolizes extracellular nucleotides,
CC including ATP, GTP, UTP and CTP (By similarity). Limits mast cell and
CC basophil responses during inflammation and during the chronic phases of
CC allergic responses by eliminating the extracellular ATP that functions
CC as signaling molecule and activates basophils and mast cells and
CC induces the release of inflammatory cytokines. Metabolizes
CC extracellular ATP in the lumen of the small intestine, and thereby
CC prevents ATP-induced apoptosis of intestinal plasmacytoid dendritic
CC cells (By similarity). Has also alkaline phosphodiesterase activity (By
CC similarity). {ECO:0000250|UniProtKB:O14638,
CC ECO:0000250|UniProtKB:Q6DYE8}.
CC -!- CATALYTIC ACTIVITY:

CC -!- SUBUNIT: Monomer and homodimer. {ECO:0000250|UniProtKB:O14638}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:O14638};
CC Single-pass type II membrane protein {ECO:0000250|UniProtKB:O14638}.
CC Apical cell membrane {ECO:0000250|UniProtKB:O14638}; Single-pass type
CC II membrane protein {ECO:0000250|UniProtKB:O14638}. Secreted
CC {ECO:0000250|UniProtKB:O14638}. Note=Detected at the cell surface of
CC basophils. Detected at the apical plasma membrane of bile duct cells.
CC Located to the apical surface in intestinal and kidney epithelial
CC cells. Secreted in serum, and in lumen of epithelial cells.
CC {ECO:0000250|UniProtKB:O14638}.
CC -!- PTM: N-glycosylated. N-glycosylation is necessary for normal transport
CC to the cell membrane, but is not the apical targeting signal.
CC {ECO:0000250|UniProtKB:P97675}.
CC -!- SIMILARITY: Belongs to the nucleotide pyrophosphatase/phosphodiesterase
CC family. {ECO:0000305}.
