General annotation (Comments)

Function

Dephosphorylates proteins phosphorylated on Ser, Thr, and Tyr residues and low molecular weight phosphatase substrate para-nitrophenylphosphate. Phosphorylates phosphatidylinositol 3,4,5-trisphosphate (PIP3) By similarity.

Catalytic activity

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

Subcellular location

Cytoplasm By similarity. Membrane; Peripheral membrane protein By similarity. Note: Localized to perinuclear region By similarity.

Sequence similarities

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

Contains 1 FYVE-type zinc finger.

Contains 1 myotubularin phosphatase domain.
