CC -!- FUNCTION: Could be involved in tyrosine phosphatase signalling
CC pathways, having MAP-kinases as substrates.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] +
CC phosphate; Xref=Rhea:RHEA:10684, Rhea:RHEA-COMP:10136, Rhea:RHEA-
CC COMP:10137, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474, ChEBI:CHEBI:46858,
CC ChEBI:CHEBI:82620; EC=3.1.3.48; Evidence={ECO:0000255|PROSITE-
CC ProRule:PRU10044};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-seryl-[protein] = L-seryl-[protein] +
CC phosphate; Xref=Rhea:RHEA:20629, Rhea:RHEA-COMP:9863, Rhea:RHEA-
CC COMP:11604, ChEBI:CHEBI:15377, ChEBI:CHEBI:29999, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:83421; EC=3.1.3.16;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-threonyl-[protein] = L-threonyl-[protein] +
CC phosphate; Xref=Rhea:RHEA:47004, Rhea:RHEA-COMP:11060, Rhea:RHEA-
CC COMP:11605, ChEBI:CHEBI:15377, ChEBI:CHEBI:30013, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:61977; EC=3.1.3.16;
CC -!- DEVELOPMENTAL STAGE: Non-dividing gametes did not express the VH-PTP13
CC gene whereas synchronously dividing vegetative cells only expressed VH-
CC PTP13 in the early G1-phase of the cycle.
CC -!- INDUCTION: By oxidative stress.
CC -!- SIMILARITY: Belongs to the protein-tyrosine phosphatase family. Non-
CC receptor class dual specificity subfamily. {ECO:0000305}.
