CC -!- FUNCTION: Isoform 2 dephosphorylates phosphorylated phytochromes, with
CC a preference toward Pfr forms, and enhances phytochrome-mediated
CC photoresponses, probably by enhancing their stability and their binding
CC affinity for light signal transducers such as NDPK2. Can use para-
CC nitrophenylphosphate (pNPP) as substrate.
CC {ECO:0000269|PubMed:15707897}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-seryl-[protein] = L-seryl-[protein] +

CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC Note=Binds 2 manganese ions per subunit. {ECO:0000250};
CC -!- ACTIVITY REGULATION: Activated by arachidonic acid (AA).
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=160 mM for pNPP (at pH 7.5 and 30 degrees Celsius)
CC {ECO:0000269|PubMed:15707897};
CC Vmax=22 umol/min/mg enzyme with pNPP as substrate (at pH 7.5 and 30
CC degrees Celsius) {ECO:0000269|PubMed:15707897};
CC Note=Experiments have been done in the presence of 100 uM arachidonic
CC acid (AA).;
CC -!- SUBUNIT: Interacts with PHYA and PHYB, mostly when they are
CC phosphorylated and in Pfr forms. {ECO:0000269|PubMed:15707897}.
CC -!- INTERACTION:
CC Q84XU2; D6RUV9: AGO1; Xeno; NbExp=2; IntAct=EBI-4445012, EBI-7498167;
CC -!- SUBCELLULAR LOCATION: [Isoform 1]: Endoplasmic reticulum membrane;
CC Multi-pass membrane protein. Nucleus membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Isoform 2]: Cytoplasm. Nucleus, nucleoplasm.
CC Nucleus speckle. Note=Cytoplasmic in darkness, but translocated to the
CC nucleus upon illumination, when associated with phytochromes into
CC speckles.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q84XU2-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q84XU2-2; Sequence=VSP_029087;
CC -!- DOMAIN: TPR repeats are required for the binding with phytochromes.
CC -!- MISCELLANEOUS: [Isoform 2]: Partial isoform 2 lacking TPR repeats
CC exhibits enhanced activity at pH 7.5 with pNPP as substrate. This
CC partial protein is in addition inhibited by okadaic acid.
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the PPP phosphatase family. PP-5 (PP-T)
CC subfamily. {ECO:0000305}.
