Bos taurus (Bovine)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

May play a role in the formation of skeletal elements derived through endochondral ossification, possibly by clearing adenosine 3',5'-bisphosphate produced by Golgi sulfotransferases during glycosaminoglycan sulfation.By similarity

Catalytic activityi

Myo-inositol phosphate + H2O = myo-inositol + phosphate.
Adenosine 3',5'-bisphosphate + H2O = adenosine 5'-phosphate + phosphate.

Cofactori

Mg2+By similarity

Enzyme regulationi

Strongly inhibited by lithium.By similarity

Pathwayi: myo-inositol biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes myo-inositol from D-glucose 6-phosphate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Inositol-3-phosphate synthase 1 (ISYNA1)
  2. Inositol monophosphatase 3 (IMPAD1), Inositol monophosphatase 1 (IMPA1)
This subpathway is part of the pathway myo-inositol biosynthesis, which is itself part of Polyol metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes myo-inositol from D-glucose 6-phosphate, the pathway myo-inositol biosynthesis and in Polyol metabolism.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
