CC -!- FUNCTION: Can dephosphorylate single and diphosphorylated synthetic
CC MAPK peptides, with preference for the phosphotyrosine and
CC diphosphorylated forms over phosphothreonine. In vitro,
CC dephosphorylates p-nitrophenyl phosphate (pNPP).
CC {ECO:0000250|UniProtKB:Q8NEJ0}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] +
