Human protein phosphatase 2C

An isolated polynucleotide selected from the group consisting of:

• a) a polynucleotide comprising a polynucleotide sequence of SEQ ID NO:23,
• b) a polynucleotide comprising a polynucleotide sequence having at least about 95% sequence identity to a polynucleotide sequence of SEQ ID NO:23, wherein the polynucleotide encodes a polypeptide that has protein phosphatase 2C activity,
• c) a polynucleotide complementary to the polynucleotide of a),
• d) a polynucleotide complementary to the polynucleotide of b), and
• e) an RNA equivalent of a)–d).
