CC -!- FUNCTION: Phosphatase that has a high activity toward
CC phosphoethanolamine (PEA) and phosphocholine (PCho) (By similarity).
CC Involved in the generation of inorganic phosphate for bone
CC mineralization (PubMed:15050893). {ECO:0000250|UniProtKB:Q8TCT1,
CC ECO:0000269|PubMed:15050893}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + phosphoethanolamine = ethanolamine + phosphate;
CC Xref=Rhea:RHEA:16089, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474,

CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q8TCT1};
CC -!- SUBCELLULAR LOCATION: Extracellular vesicle
CC {ECO:0000250|UniProtKB:Q8R2H9}. Note=Localizes to special class of
CC extracellular vesicles, named matrix vesicles (MVs), which are released
CC by osteogenic cells. {ECO:0000250|UniProtKB:Q8R2H9}.
CC -!- TISSUE SPECIFICITY: Expressed at sites of mineralization in bone and
CC cartilage. Highly expressed in hypertrophic chondrocytes compared to
CC non-chondrogenic tissues. Expressed in chondrocytes but not in heart,
CC liver, lung, kidney, spleen, muscle, adipose tissues not duodenum. In
CC diaphyseal cortical bone, it is expressed in the osteoid layer of the
CC periosteum, forming surfaces of growing osteons, and newly formed
CC osteocytes, whereas it is not expressed in the endosteum and closed
CC osteons. In growth plate cartilage, it is limited to the early
CC hypertrophic chondrocytes and the ossification groove of Ranvier.
CC Highly expressed on the mineralization surfaces of the cartilage
CC remnants and trabecular bone within the primary spongiosa. Expressed in
CC 17-day-old embryonic calvaria, the osteoid present on the
CC intramembranous and periosteal bone surfaces but not in soft tissues
CC examined. {ECO:0000269|PubMed:15050893, ECO:0000269|PubMed:9990301}.
CC -!- INDUCTION: Up-regulated 5-fold during chondrocyte terminal
CC differentiation. {ECO:0000269|PubMed:9990301}.
CC -!- SIMILARITY: Belongs to the HAD-like hydrolase superfamily. PHOSPHO
CC family. {ECO:0000305}.
