|---|---|---|
| transcription corepressor activity | molecular function | A transcription coregulator activity that represses or decreases the transcription of specific gene sets via binding to a DNA-bound DNA-binding transcription factor, either on its own or as part of a complex. Corepressors often act by altering chromatin structure and modifications. For example, one class of transcription corepressors modifies chromatin structure through covalent modification of histones. A second class remodels the conformation of chromatin in an ATP-dependent fashion. A third class modulates interactions of DNA-bound DNA-binding transcription factors with other transcription coregulators. [GOC:txnOH-2018, PMID:10213677, PMID:16858867] |
| protein binding | molecular function | Binding to a protein. [GOC:go_curators] |
| nucleosome binding | molecular function | Binding to a nucleosome, a complex comprised of DNA wound around a multisubunit core and associated proteins, which forms the primary packing unit of DNA into higher order structures. [GOC:mah] |
| histone H3K27 methyltransferase activity | molecular function | Catalysis of the reaction: S-adenosyl-L-methionine + histone H3 L-lysine (position 27) = S-adenosyl-L-homocysteine + histone H3 N6-methyl-L-lysine (position 27). This reaction is the addition of a methyl group to the lysine residue at position 27 of the histone H3 protein. [GOC:ai] |
| molecular condensate scaffold activity | molecular function | Binding and bringing together two or more macromolecules in contact, permitting those molecules to organize as a molecular condensate. [PMID:28225081] |
| histone H3K27 trimethyltransferase activity | molecular function | Catalysis of the reaction: L-lysyl27-[histone H3] + 3 S-adenosyl-L-methionine = 3 H+ + N6,N6,N6-trimethyl-L-lysyl27-[histone H3] + 3 S-adenosyl-L-homocysteine. This reaction is the successive addition of three methyl groups to the unmethylated lysine residue at position 27 of histone H3, producing histone H3K27me3. [RHEA:60292] |
| chromatin binding | molecular function | Binding to chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase. [GOC:jl, ISBN:0198506732, PMID:20404130] |
This protein is located in 2 target(s):
| Target | Category | Definition |
|---|---|---|
| chromosome, telomeric region | cellular component | The end of a linear chromosome, required for the integrity and maintenance of the end. A chromosome telomere usually includes a region of telomerase-encoded repeats the length of which rarely exceeds 20 bp each and that permits the formation of a telomeric loop (T-loop). The telomeric repeat region is usually preceded by a sub-telomeric region that is gene-poor but rich in repetitive elements. Some telomeres only consist of the latter part (for eg. D. melanogaster telomeres). [GOC:elh] |
| nucleoplasm | cellular component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |

| 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] |

| heterochromatin | cellular component | A compact and highly condensed form of chromatin that is refractory to transcription. [PMID:32017156] |
| ESC/E(Z) complex | cellular component | A multimeric protein complex that can methylate lysine-27 and lysine-9 residues of histone H3. In Drosophila the core subunits of the complex include ESC, E(Z), CAF1 (NURF-55) and SU(Z)12. In mammals the core subunits of the complex include EED, EZH2, SUZ12 and RBBP4.
