This protein enables 3 target(s):
| Target | Category | Definition |
|---|---|---|
| protein binding | molecular function | Binding to a protein. [GOC:go_curators] |
| enzyme regulator activity | molecular function | Binds to and modulates the activity of an enzyme. [GOC:dph, GOC:mah, GOC:tb] |
| ubiquitin protein ligase binding | molecular function | Binding to a ubiquitin protein ligase enzyme, any of the E3 proteins. [GOC:vp] |
This protein is located in 5 target(s):
| Target | Category | Definition |
|---|---|---|
| extracellular region | cellular component | The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. [GOC:go_curators] |
| nucleoplasm | cellular component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
| cytosol | cellular component | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl] |
| membrane | cellular component | A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. [GOC:dos, GOC:mah, ISBN:0815316194] |
| azurophil granule lumen | cellular component | The volume enclosed by the membrane of an azurophil granule, a primary lysosomal granule found in neutrophil granulocytes that contains a wide range of hydrolytic enzymes and is released into the extracellular fluid. [GOC:bf, PMID:17152095] |
This protein is active in 2 target(s):
| Target | Category | Definition |
|---|---|---|
| nucleus | cellular component | 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. [GOC:go_curators] |
| proteasome storage granule | cellular component | An aggregation of proteasome core protease (CP) and regulatory particle (RP) complexes that localizes in the cytoplasm as dot-like structures when cells are in a quiescent state. [GOC:krc, GOC:rb, PMID:18504300, PMID:30204036] |
This protein is part of 4 target(s):
| Target | Category | Definition |
|---|---|---|
| proteasome complex | cellular component | 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. [GOC:rb, Wikipedia:Proteasome] |
| proteasome regulatory particle | cellular component | 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. [GOC:mtg_sensu, GOC:rb] |
| proteasome accessory complex | cellular component | A protein complex, that caps one or both ends of the proteasome core complex and regulates entry into, or exit from, the proteasome core complex. [GOC:mtg_sensu] |
| proteasome regulatory particle, base subcomplex | cellular component | The subcomplex of the proteasome regulatory particle that directly associates with the proteasome core complex. [GOC:mtg_sensu, GOC:rb] |
This protein is involved in 2 target(s):
| Target | Category | Definition |
|---|---|---|
| regulation of protein catabolic process | biological process | Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of a protein by the destruction of the native, active configuration, with or without the hydrolysis of peptide bonds. [GOC:go_curators, GOC:jl] |
| proteasome-mediated ubiquitin-dependent protein catabolic process | biological process | 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.
