CC -!- FUNCTION: Protein phosphatase that catalyzes the dephosphorylation of
CC the C-terminal domain of RNA polymerase II. Plays a role in RNA
CC processing and termination. Plays a role in pre-mRNA polyadenylation
CC via its interaction with SYMPK. {ECO:0000269|PubMed:15659578}.
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 ChEBI:CHEBI:83421; EC=3.1.3.16;
CC -!- CATALYTIC ACTIVITY:

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 -!- SUBUNIT: Interacts with GTF2B (via C-terminus); this interaction is
CC inhibited by SYMPK. Interacts with RB1. Interacts with CD226. Interacts
CC with SYMPK. {ECO:0000250|UniProtKB:Q9NP77}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}.
CC Note=Predominantly in the cytosol. {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q9CY97-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9CY97-2; Sequence=VSP_033006;
CC -!- TISSUE SPECIFICITY: Highly expressed in the brain. Expressed at low
CC level in most tissues. {ECO:0000269|PubMed:15659578}.
CC -!- DEVELOPMENTAL STAGE: At 10.5 dpc, low level expression detected
CC throughout the embryo with relative accumulation in spinal cord and
CC brain folds. At 13.5 dpc, highly expressed in the CNS both in the
CC ventricular (mitotic) and marginal (post mitotic) zones, in the PNS in
CC dorsal root and trigeminal ganglia, and the developing gut. During
CC development, expression in the central nervous system and peripheral
CC nervous system persists, and expression in the intestine is further
CC induced. Expression in the intestine is observed throughout the mucosal
CC villi, which contains epithelial cells and other cell types. High
CC expression is also detected in the lens. No expression is seen in other
CC tissues such as liver, lung, bone, cardiac and skeletal muscles.
CC {ECO:0000269|PubMed:15659578}.
CC -!- SIMILARITY: Belongs to the SSU72 phosphatase family. {ECO:0000305}.
