molecular function
    GO:0003993    acid phosphatase activity    Catalysis of the reaction: an orthophosphoric monoester + H2O = an alcohol + phosphate, with an acid pH optimum.
    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:0004726    non-membrane spanning protein tyrosine phosphatase activity    Catalysis of the reaction: non-membrane spanning protein tyrosine phosphate + H2O = non-membrane spanning protein tyrosine + 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:0004725    protein tyrosine phosphatase activity    Catalysis of the reaction: protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
biological process
    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.
