Long description
The product of the PRL-1 gene (alternate gene names PTP4A1 Synonyms:ÊDKFZp779M0721, hPTPCAAX1) is a protein tyrosine phosphatase also known as phosphatase of regenerating liver, Protein tyrosine phosphatase type IVA, member 1, PTPCAAX1 or Hypothetical protein DKFZp779M0721. Protein tyrosine phosphatases play important roles in the regulation of cell growth, development, and differentiation. PRL-1 is one of the most interesting immediate early growth response genes in regenerating liver. The gene encodes a novel 20-kDa nuclear protein tyrosine phosphatase. Other than the signature sequence for PTPases, PRL-1 is not homologous to either the dual specificity PTPases (cdc25 and MKP-1) or monospecific PTPases. PRL-1 is elevated throughout the major proliferative phase of liver regeneration when hepatocytes and nonparenchymal cells in the liver are rapidly proliferating. PR-1 is also expressed at high levels in other proliferating cells including tumor cell lines such as hepatomas. PRL-1-transfected cells showed altered growth characteristics, including a faster doubling time, growth to a greater saturation density, altered morphology, and evidence of anchorage-independent growth. Overexpression of human PRL-1 in epithelial cells results in tumor formation in_x000B_nude mice.

Application
Useful for the study of enzyme kinetics, regulation, to dephosphorylate target substrates and for screening inhibitors.
Antibody's suited for
Antibody should be used at a 1:1000 dilution to provide for 10 miniblots in Western blotting and dot blots. Antibody detects only phosphorylated protein and does not detect non-phosphorylated protein as shown by the lack of ability of a non-phospho peptide to block the antibody activity. Optimal concentration may be evaluated by serial dilutions.
Storage

Description
Enzymes are cleaving the substrate. If the substrate is DNA they are called restriction enzymes. Activating enzymes will cut off the domain that is biological active to become functional.
