Enables
This protein enables 3 target(s):
| Target | Category | Definition |
|---|
| transcription corepressor binding | molecular function | Binding to a transcription corepressor, a protein involved in negative regulation of transcription via protein-protein interactions with transcription factors and other proteins that negatively regulate transcription. Transcription corepressors do not bind DNA directly, but rather mediate protein-protein interactions between repressing transcription factors and the basal transcription machinery. [GOC:krc] |
| protein binding | molecular function | Binding to a protein. [GOC:go_curators] |
| ubiquitin protein ligase binding | molecular function | Binding to a ubiquitin protein ligase enzyme, any of the E3 proteins. [GOC:vp] |
Located In
This protein is located in 2 target(s):
| Target | Category | Definition |
|---|
| 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] |
Part Of
This protein is part of 4 target(s):
| Target | Category | Definition |
|---|
| Cul2-RING ubiquitin ligase complex | cellular component | A ubiquitin ligase complex in which a cullin from the Cul2 subfamily and a RING domain protein form the catalytic core; substrate specificity is conferred by an elongin-BC adaptor and a SOCS/BC box protein. [PMID:15571813, PMID:15688063] |
| Cul5-RING ubiquitin ligase complex | cellular component | A ubiquitin ligase complex in which a cullin from the Cul5 subfamily and a RING domain protein form the catalytic core; substrate specificity is conferred by an elongin-BC adaptor and a SOCS/BC box protein. [PMID:15571813, PMID:15688063] |
| elongin complex | cellular component | A transcription elongation factor complex that suppresses RNA polymerase II pausing, and may act by promoting proper alignment of the 3'-end of nascent transcripts with the polymerase catalytic site. Consists of a transcriptionally active Elongin A subunit (about 100 kDa) and two smaller Elongin B (about 18 kDa) and Elongin C (about 15 kDa) subunits. [PMID:12676794] |
| VCB complex | cellular component | A protein complex that possesses ubiquitin ligase activity; the complex is usually pentameric; for example, in mammals the subunits are pVHL, elongin B, elongin C, cullin-2 (Cul2), and Rbx1. [GOC:mah, PMID:11865071] |
Involved In
This protein is involved in 6 target(s):
| Target | Category | Definition |
|---|
| transcription initiation at RNA polymerase II promoter | biological process | A transcription initiation process that takes place at a RNA polymerase II gene promoter. Messenger RNAs (mRNA) genes, as well as some non-coding RNAs, are transcribed by RNA polymerase II. [GOC:mah, GOC:txnOH] |
| transcription elongation by RNA polymerase II | biological process | The extension of an RNA molecule after transcription initiation and promoter clearance at an RNA polymerase II promoter by the addition of ribonucleotides catalyzed by RNA polymerase II. [GOC:mah, GOC:txnOH] |
| protein ubiquitination | biological process | The process in which one or more ubiquitin groups are added to a protein. [GOC:ai] |
| positive regulation of proteasomal ubiquitin-dependent protein catabolic process | biological process | Any process that activates or increases the frequency, rate or extent of 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. [GOC:mah] |
| protein-containing complex assembly | biological process | The aggregation, arrangement and bonding together of a set of macromolecules to form a protein-containing complex. [GOC:jl] |
| target-directed miRNA degradation | biological process | The process in which a miRNA is targeted for degradation by a non-coding RNA or mRNA. The binding of an RNA to a target miRNA within a RISC complex results in either ubiquitin-mediated degradation of AGO protein or the displacement of the 3' end of the miRNA, exposing it to nucleases.
