Summary
BPNT1, also called bisphosphate 3-prime-nucleotidase, or BPntase, is a member of a magnesium-dependent phosphomonoesterase family. Lithium, a major drug used to treat manic depression, acts as an uncompetitive inhibitor of BPntase. The predicted human protein is 92% identical to mouse BPntase. BPntase's physiologic role in nucleotide metabolism may be regulated by inositol signaling pathways. The inhibition of human BPntase may account for lithium-induced nephrotoxicity.

Comments

Comment Type Description
Alternative Products Event=Alternative splicing; Named isoforms=4; Name=1; IsoId=O95861-1; Sequence=Displayed; Name=2; IsoId=O95861-2; Sequence=VSP_009937; Note=No experimental confirmation available.; Name=3; IsoId=O95861-3; Sequence=VSP_054807; Name=4; IsoId=O95861-4; Sequence=VSP_054808;
Catalytic Activity Adenosine 3',5'-bisphosphate + H(2)O = adenosine 5'-phosphate + phosphate.
Cofactor Name=Mg(2+); Xref=ChEBI
Enzyme Regulation Uncompetitive inhibition by micromolar concentrations of lithium. Competitive inhibition by inositol 1,4- bisphosphate.
Function Converts adenosine 3'-phosphate 5'-phosphosulfate (PAPS) to adenosine 5'-phosphosulfate (APS) and 3'(2')-phosphoadenosine 5'- phosphate (PAP) to AMP. Has 1000-fold lower activity towards inositol 1,4-bisphosphate (Ins(1,4)P2) and inositol 1,3,4- trisphosphate (Ins(1,3,4)P3), but does not hydrolyze Ins(1)P, Ins(3,4)P2, Ins(1,3,4,5)P4 or InsP6.
Similarity Belongs to the inositol monophosphatase family.
Tissue Specificity Highly expressed in kidney, liver, pancreas and heart. Detected at lower levels in brain, placenta, lung and skeletal muscle.
