PFAM accession number:PF00459
Interpro abstract (IPR000760): It has been shown that several proteins share two sequence motifs [(PUBMED:1660408)]. Two of these proteins, vertebrate and plant inositol monophosphatase (EC, and vertebrate inositol polyphosphate 1-phosphatase (EC, are enzymes of the inositol phosphate second messenger signalling pathway, and share similar enzyme activity. Both enzymes exhibit an absolute requirement for metal ions (Mg2+ is preferred), and their amino acid sequences contain a number of conserved motifs, which are also shared by several other proteins related to MPTASE (including products of fungal QaX and qutG, bacterial suhB and cysQ, and yeast hal2) [(PUBMED:7761465)]. The function of the other proteins is not yet clear, but it is suggested that they may act by enhancing the synthesis or degradation of phosphorylated messenger molecules [(PUBMED:1660408)]. Structural analysis of these proteins has revealed a common core of 155 residues, which includes residues essential for metal binding and catalysis. An interesting property of the enzymes of this family is their sensitivity to Li+. The targets and mechanism of action of Li+ are unknown, but overactive inositol phosphate signalling may account for symptoms of manic depression [(PUBMED:2553271)].
