Structure of human PRL-3, the phosphatase associated with cancer metastasis
Structural highlights
FunctionTP4A3_HUMAN Protein tyrosine phosphatase which stimulates progression from G1 into S phase during mitosis. Enhances cell proliferation, cell motility and invasive activity, and promotes cancer metastasis. May be involved in the progression of cardiac hypertrophy by inhibiting intracellular calcium mobilization in response to angiotensin II.[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedPRL-3, a novel class protein of prenylated tyrosine phosphatase, is important in cancer metastasis. Due to its high levels of expression in metastatic tumors, PRL-3 may constitute a useful marker for metastasis and might be a new therapeutic target. Here, we present the solution structure of the phosphatase domain of a human PRL-3 (residues 1-162) in phosphate-free state. The nuclear magnetic resonance (NMR) structure of PRL-3 is similar to that of other known phosphatases with minor differences in the secondary structure. But the conformation and flexibility of the loops comprising the active site differ significantly. When phosphate ions or sodium orthovanadate, which is a known inhibitor, are added to the apo PRL-3, the NMR signals from the residues in the active site appeared and could be assigned, indicating that the conformation of the residues has been stabilized.
