CC -!- FUNCTION: Exhibits 3'-nucleotidase activity toward adenosine 3',5'-
CC bisphosphate (PAP), namely hydrolyzes adenosine 3',5'-bisphosphate into
CC adenosine 5'-monophosphate (AMP) and a phosphate. May play a role in
CC the formation of skeletal elements derived through endochondral
CC ossification, possibly by clearing adenosine 3',5'-bisphosphate
CC produced by Golgi sulfotransferases during glycosaminoglycan sulfation.
CC Has no activity toward 3'-phosphoadenosine 5'-phosphosulfate (PAPS) or
CC inositol phosphate (IP) substrates including I(1)P, I(1,4)P2,
CC I(1,3,4)P3, I(1,4,5)P3 and I(1,3,4,5)P4.
CC {ECO:0000250|UniProtKB:Q80V26}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenosine 3',5'-bisphosphate + H2O = AMP + phosphate;
CC Xref=Rhea:RHEA:10040, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:58343, ChEBI:CHEBI:456215; EC=3.1.3.7;
CC Evidence={ECO:0000250|UniProtKB:Q80V26};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC -!- ACTIVITY REGULATION: Strongly inhibited by lithium.
CC {ECO:0000250|UniProtKB:Q80V26}.
CC -!- PATHWAY: Sulfur metabolism. {ECO:0000250|UniProtKB:Q80V26}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus {ECO:0000269|PubMed:18695242}.
CC Golgi apparatus, trans-Golgi network membrane
CC {ECO:0000269|PubMed:18695242}; Single-pass type II membrane protein
CC {ECO:0000255, ECO:0000269|PubMed:18695242}. Note=The catalytic core is
CC predicted to reside within the Golgi lumen.
CC {ECO:0000269|PubMed:18695242}.
CC -!- PTM: Contains N-linked glycan resistant to endoglycosydase H.
CC {ECO:0000269|PubMed:18695242}.
CC -!- DISEASE: Chondrodysplasia with joint dislocations, GPAPP type (CDP-
CC GPAPP) [MIM:614078]: A condition consisting of congenital joint
CC dislocations, chondrodysplasia with short stature, micrognathia and
CC cleft palate, and a distinctive face. {ECO:0000269|PubMed:21549340}.
CC Note=The disease is caused by variants affecting the gene represented
CC in this entry.
CC -!- SIMILARITY: Belongs to the inositol monophosphatase superfamily.
