Protein attributes

Sequence length	750 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Major phosphatase responsible with PTP3 for tyrosine dephosphorylation of MAP kinase HOG1 to inactivate its activity. May also be involved in the regulation of MAP kinase FUS3. May be implicated in the ubiquitin-mediated protein degradation. Ref.6 Ref.7
Catalytic activity	Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
Subunit structure	Interacts with HOG1. Ref.6 Ref.7
Subcellular location	Cytoplasm. Nucleus Ref.8.
Miscellaneous	Present with 149 molecules/cell in log phase SD medium.
Sequence similarities	Belongs to the protein-tyrosine phosphatase family. Non-receptor class subfamily. Contains 1 tyrosine-protein phosphatase domain.
