RG   NIH - Xenopus Gene Collection (XGC) project;
RL   Submitted (OCT-2004) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Catalytically inactive phosphatase.
CC       {ECO:0000250|UniProtKB:Q8WUJ0}.
CC   -!- SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Non-
CC       receptor class subfamily. {ECO:0000305}.
CC   -!- CAUTION: Contains a Gly residue instead of a conserved Cys residue at
CC       position 120 in the dsPTPase catalytic loop which renders it
CC       catalytically inactive as a phosphatase (By similarity). The binding
CC       pocket is however sufficiently preserved to bind phosphorylated
CC       substrates, and may protect them from phosphatases (By similarity).
CC       {ECO:0000250|UniProtKB:Q8WUJ0}.
