FunFam 3: 26S proteasome non-ATPase regulatory subunit 4

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 4 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

2 P55035 (/IPI) P55035 (/IPI)
Zinc ion binding GO:0008270
Interacting selectively and non-covalently with zinc (Zn) ions.
2 P55035 (/IDA) P55035 (/IDA)
Polyubiquitin modification-dependent protein binding GO:0031593
Interacting selectively and non-covalently with a protein upon poly-ubiquitination of the target protein.

There are 6 GO terms relating to "biological process"

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
Mitotic sister chromatid segregation GO:0000070
The cell cycle process in which replicated homologous chromosomes are organized and then physically separated and apportioned to two sets during the mitotic cell cycle. Each replicated chromosome, composed of two sister chromatids, aligns at the cell equator, paired with its homologous partner. One homolog of each morphologic type goes into each of the resulting chromosome sets.
2 P55035 (/IMP) P55035 (/IMP)
Circadian rhythm GO:0007623
Any biological process in an organism that recurs with a regularity of approximately 24 hours.
2 P55035 (/TAS) P55035 (/TAS)
Toll signaling pathway GO:0008063
A series of molecular signals initiated by the binding of an extracellular ligand to the receptor Toll on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.
2 P55035 (/TAS) P55035 (/TAS)
Proteasome-mediated ubiquitin-dependent protein catabolic process GO:0043161
The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome.
2 P55035 (/IC) P55035 (/IC)
Proteasome-mediated ubiquitin-dependent protein catabolic process GO:0043161
The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome.
2 P55035 (/IGI) P55035 (/IGI)
Proteasome-mediated ubiquitin-dependent protein catabolic process GO:0043161
The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome.

GO Term Annotations Evidence
Proteasome complex GO:0000502
A large multisubunit complex which catalyzes protein degradation, found in eukaryotes, archaea and some bacteria. In eukaryotes, this complex consists of the barrel shaped proteasome core complex and one or two associated proteins or complexes that act in regulating entry into or exit from the core.
2 P55035 (/IDA) P55035 (/IDA)
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.
2 P55035 (/HDA) P55035 (/HDA)
Nucleoplasm GO:0005654
That part of the nuclear content other than the chromosomes or the nucleolus.
2 P55035 (/TAS) P55035 (/TAS)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
2 P55035 (/HDA) P55035 (/HDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
2 P55035 (/TAS) P55035 (/TAS)
Proteasome regulatory particle GO:0005838
A multisubunit complex, which caps one or both ends of the proteasome core complex. This complex recognizes and unfolds ubiquitinated proteins, and translocates them to the proteasome core complex.
2 P55035 (/IDA) P55035 (/IDA)
Proteasome regulatory particle GO:0005838
A multisubunit complex, which caps one or both ends of the proteasome core complex. This complex recognizes and unfolds ubiquitinated proteins, and translocates them to the proteasome core complex.
2 P55035 (/ISS) P55035 (/ISS)
Proteasome regulatory particle, base subcomplex GO:0008540
The subcomplex of the proteasome regulatory particle that directly associates with the proteasome core complex.
