Descriptions

Histone acetyltransferase p300 (EP300, also known as p300) is an enzyme that functions as histone acetyltransferase that regulates transcription of genes. It plays an essential role in regulating cell growth and division, prompting cells to mature and assume specialized functions, and preventing the growth of cancerous tumors. EP300 contains several domains including the CH1, KIX, CH3 (ZZ-TAZ2) and NCBD domains, which enable the interaction with numerous transcription factors and the basal transcription machinery. The activity of EP300 is regulated by its RING domain, or autoinhibitory loop within the HAT domain. The RING domain sterically occludes the HAT active site, and the displacement of the RING domain coupled to autoacetylation in trans results in full catalytic activation. Furthermore, the catalytic activity of EP300 is also regulated through acetylation / deacetylation of the autoinhibitory loop in the HAT domain, which impedes the acetyltransferase activity of EP300 but releases the inhibition upon hyper autoacetylation.

Name Definition
chromatin The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
histone acetyltransferase complex A protein complex that possesses histone acetyltransferase activity.
nuclear body Extra-nucleolar nuclear domains usually visualized by confocal microscopy and fluorescent antibodies to specific proteins.
nucleoplasm That part of the nuclear content other than the chromosomes or the nucleolus.
nucleus 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.

protein-containing complex A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
RNA polymerase II transcription regulator complex A transcription factor complex that acts at a regulatory region of a gene transcribed by RNA polymerase II.
transcription regulator complex A protein complex that is capable of associating with DNA by direct binding, or via other DNA-binding proteins or complexes, and regulating transcription.

transcription coactivator activity A transcription coregulator activity that activates or increases 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. Coactivators often act by altering chromatin structure and modifications. For example, one class of transcription coactivators 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. A fourth class of coactivator activity is the bridging of a DNA-binding transcription factor to the general (basal) transcription machinery. The Mediator complex, which bridges sequence-specific DNA binding transcription factors and RNA polymerase, is also a transcription coactivator.
transcription coactivator binding Binding to a transcription coactivator, a protein involved in positive regulation of transcription via protein-protein interactions with transcription factors and other proteins that positively regulate transcription.

transcription corepressor activity 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.
