Chain A   (PTPRG_HUMAN | P23470)
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:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    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.
    GO:0005001    transmembrane receptor protein tyrosine phosphatase activity    Combining with a signal and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity by 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:0010633    negative regulation of epithelial cell migration    Any process that stops, prevents, or reduces the frequency, rate or extent of epithelial cell migration.
    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.
    GO:1903385    regulation of homophilic cell adhesion    Any process that modulates the frequency, rate or extent of homophilic cell adhesion.
    GO:0007169    transmembrane receptor protein tyrosine kinase signaling pathway    A series of molecular signals initiated by the binding of an extracellular ligand to a receptor on the surface of the target cell where the receptor possesses tyrosine kinase activity, and ending with regulation of a downstream cellular process, e.g. transcription.
cellular component
    GO:0070062    extracellular exosome    A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0005887    integral component of plasma membrane    The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
