CLASS OF ENZYMES
Protein Tyrosine Phosphatase; Protein-tyrosine-phosphatase; Tyrosine phosphatase; Protein tyrosine phosphatases; Protein tyrosine phosphatase sigma; Non-receptor protein tyrosine phosphatase; EC 3.1.3.48; Protein-tyrosine-phosphate phosphohydrolase; Protein tyrosine phosphatase nonreceptor type 22
Protein tyrosine phosphatases are a group of enzymes that remove phosphate groups from phosphorylated tyrosine residues on proteins. Protein tyrosine (pTyr) phosphorylation is a common post-translational modification that can create novel recognition motifs for protein interactions and cellular localization, affect protein stability, and regulate enzyme activity.
