General annotation (Comments)

Function

Regulates mitogenic signal transduction by dephosphorylating both Thr and Tyr residues on MAP kinases ERK1 and ERK2 By similarity.

Catalytic activity

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

A phosphoprotein + H2O = a protein + phosphate.

Subunit structure

Hollow spherical complex composed of 24 subunits with pseudooctahedral symmetry, has a tetramer as the basic unit By similarity.

Subcellular location

Nucleus By similarity.

Tissue specificity

Expressed at moderate levels in nearly all tissues and cells including brain, spleen, and testes with the higher expression in the heart and lung and lower expression in skeletal muscle and kidney. Undetectable in liver. Expressed in many areas of the brain with very strong expression in the hippocampus, piriform cortex, and the suprachiasmatic nucleus.

Induction

By mitogens and by stress.

Post-translational modification

Phosphorylation in the C-terminus by ERK1/2 inhibits proteasomal degradation and stabilizes the protein By similarity.

Sequence similarities

Belongs to the protein-tyrosine phosphatase family. Non-receptor class dual specificity subfamily.

Contains 1 rhodanese domain.

Contains 1 tyrosine-protein phosphatase domain.
