Protein attributes

Sequence length435 AA.
Sequence statusComplete.
Sequence processingThe displayed sequence is not processed.
Protein existenceEvidence at protein level.

General annotation (Comments)

Function

May play an important role in CKII- and p60c-src-induced signal transduction cascades By similarity.

Catalytic activity

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

Subcellular location

Endoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side. Ref.8

Post-translational modification

Oxidized on Cys-215; the Cys-SOH formed in response to redox signaling reacts with the alpha-amido of the following residue to form a 4-amino-3-isothiazolidinone serine cross-link, triggering a conformational change that inhibits substrate binding and activity. The active site can be restored by reduction.

Sequence similarities

Belongs to the protein-tyrosine phosphatase family. Non-receptor class 1 subfamily.

Contains 1 tyrosine-protein phosphatase domain.
