Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (PTN7_HUMAN | P35236)
molecular function
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0016791    phosphatase activity    Catalysis of the hydrolysis of phosphoric monoesters, releasing inorganic phosphate.
    GO:0004721    phosphoprotein phosphatase activity    Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. Together with protein kinases, these enzymes control the state of phosphorylation of cell proteins and thereby provide an important mechanism for regulating cellular activity.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0004725    protein tyrosine phosphatase activity    Catalysis of the reaction: protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
biological process
    GO:0016311    dephosphorylation    The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.
    GO:0035335    peptidyl-tyrosine dephosphorylation    The removal of phosphoric residues from peptidyl-O-phospho-tyrosine to form peptidyl-tyrosine.
    GO:0006470    protein dephosphorylation    The process of removing one or more phosphoric residues from a protein.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0009898    cytoplasmic side of plasma membrane    The leaflet the plasma membrane that faces the cytoplasm and any proteins embedded or anchored in it or attached to its surface.
    GO:0005856    cytoskeleton    Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
