Abstract
An object of the present invention is to provide a recombinant LPA phosphates capable of specifically hydrolyzing LPA, which is useful for elucidation of the metabolic pathway of LPA, and also for diagnosis and treatment of various diseases with which LPA is associated. The present invention also provides for a method capable of simply and inexpensively determining LPA associated with various diseases. The present invention also provides for a kit for determination suitable for the method. The present invention has succeeded in purifying the LPA phosphatase using bovine brain as a raw material, and further in cloning human LPA phosphatase gene. The present invention specifically relates to a DNA encoding a peptide comprising the amino acid sequence of SEQ ID NO:1; a DNA comprising the nucleotide sequence of SEQ ID NO:2; a protein encoded by the DNA; and expression vector carrying the DNA; a transformant harboring the expression vector; a method for producing a recombinant lysophosphatidic acid phosphatase by the transformant; a method for determination of LPA by the protein; a determination reagent for LPA by the protein; a kit for diagnosis, comprising the reagent for determination, and the like.
