Molecular Cloning and Characterization of a Novel Human Protein Phosphatase 2C cDNA (PP2C epsilon*)

Mol Biol Rep. 2004 Sep;31(3):197-202. doi: 10.1023/b:mole.0000043624.96006.eb.


We have isolated a novel cDNA from the human fetal brain cDNA library with homology to the Mg2+ -dependent serine/threonine protein phosphatase 2C (PP2C) family. The cDNA is 3055 bp in length, and the predicted coding region encodes a 360-amino-acid protein, which shows 99% identity to the PP2C epsilon from rat and mouse. Then we term it human PP2C epsilon gene. The gene is mapped to chromosome 3q26.1 and contains 4 exons. RT-PCR analysis shows that the PP2C epsilon is widely expressed in human tissues and the expression levels in heart, placenta, lung, liver, kidney, and pancreas are relatively high.
