The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:

"

FunFam 23: Protein phosphatase, Mg2+/Mn2+-dependent, 1G

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 5 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).

Protein serine/threonine phosphatase activity GO:0004722
Catalysis of the reaction: protein serine phosphate + H2O = protein serine + phosphate, and protein threonine phosphate + H2O = protein threonine + phosphate.
4 O15355 (/IDA) O15355 (/IDA) O15355 (/IDA) O15355 (/IDA)
Protein serine/threonine phosphatase activity GO:0004722
Catalysis of the reaction: protein serine phosphate + H2O = protein serine + phosphate, and protein threonine phosphate + H2O = protein threonine + phosphate.
4 O15355 (/TAS) O15355 (/TAS) O15355 (/TAS) O15355 (/TAS)
Phosphoprotein phosphatase activity GO:0004721
Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. Together with protein kinases, these enzymes control the state of phosphorylation of cell proteins and thereby provide an important mechanism for regulating cellular activity.
1 Q61074 (/IDA)
Protein serine/threonine phosphatase activity GO:0004722
Catalysis of the reaction: protein serine phosphate + H2O = protein serine + phosphate, and protein threonine phosphate + H2O = protein threonine + phosphate.

Protein dephosphorylation GO:0006470
The process of removing one or more phosphoric residues from a protein.
4 O15355 (/TAS) O15355 (/TAS) O15355 (/TAS) O15355 (/TAS)
Cell cycle arrest GO:0007050
A regulatory process that halts progression through the cell cycle during one of the normal phases (G1, S, G2, M).
4 O15355 (/TAS) O15355 (/TAS) O15355 (/TAS) O15355 (/TAS)
Peptidyl-threonine dephosphorylation GO:0035970
The removal of phosphoric residues from peptidyl-O-phospho-L-threonine to form peptidyl-threonine.
4 O15355 (/IDA) O15355 (/IDA) O15355 (/IDA) O15355 (/IDA)
Central nervous system development GO:0007417
The process whose specific outcome is the progression of the central nervous system over time, from its formation to the mature structure. The central nervous system is the core nervous system that serves an integrating and coordinating function. In vertebrates it consists of the brain and spinal cord. In those invertebrates with a central nervous system it typically consists of a brain, cerebral ganglia and a nerve cord.

Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
