What does p300 protein do?
Function. p300 HAT functions as histone acetyltransferase that regulates transcription via chromatin remodeling, and is important in the processes of cell proliferation and differentiation. It mediates cAMP-gene regulation by binding specifically to phosphorylated CREB protein.
What is p300 genetics?
Collapse Section. The EP300 gene provides instructions for making a protein called p300, which regulates the activity of many genes in tissues throughout the body. This protein plays an essential role in controlling cell growth and division and prompting cells to mature and take on specialized functions (differentiate) …
What is p300 Acetylate?
p300 Acetyltransferase Activity. p300/CBP has a central acetyltransferase (also called HAT) domain that catalyzes the reaction in which the acetyl group from acetyl-CoA is transferred to a protein lysine side chain. p300/CBP has the ability to acetylate a wide variety of proteins (see Supporting Information Table 1).
Is p300 a hat?
The transcriptional coactivator p300 is a histone acetyltransferase (HAT) whose function is critical for regulating gene expression in mammalian cells.
Is BRD4 a transcription factor?
Consistent with its pleiotropic activities in regulating the cell cycle, BRD4 also plays a critical role in regulating differentiation and development; however, BRD4 is not a general transcription factor.
What does acetylation do to genes?
Histone acetylation is a critical epigenetic modification that changes chromatin architecture and regulates gene expression by opening or closing the chromatin structure. It plays an essential role in cell cycle progression and differentiation.
What is P300 transcription?
The transcriptional co-activator p300 is a histone acetyltransferase (HAT) that is typically recruited to transcriptional enhancers and regulates gene expression by acetylating chromatin.
What is a Bromodomain protein BRD4?
Bromodomain-containing protein 4 (BRD4) is an epigenetic reader that recognizes histone proteins and acts as a transcriptional regulator to trigger tumor growth and the inflammatory response. The pan-bromodomain and extra-terminal domain (BET) inhibitor, (+)-JQ1 (1), was reported to inhibit angiogenesis.
Where is BRD4 located?
Bromodomain-containing protein 4 is a protein that in humans is encoded by the BRD4 gene. BRD4 is a member of the BET (bromodomain and extra terminal domain) family, which also includes BRD2, BRD3, and BRDT….

What is the function of the p300 gene?
2033 – Gene ResultEP300 E1A binding protein p300 [ (human)] This gene encodes the adenovirus E1A-associated cellular p300 transcriptional co-activator protein. It functions as histone acetyltransferase that regulates transcription via chromatin remodeling and is important in the processes of cell proliferation and differentiation.
How does the p300 protein make DNA ready for transcription?
The p300 protein ensures the DNA is ready for transcription by attaching a small molecule called an acetyl group (a process called acetylation) to proteins called histones. Histones are structural proteins that bind DNA and give chromosomes their shape.
What are the diseases associated with the EP300 gene?
GeneCards Summary for EP300 Gene EP300 (E1A Binding Protein P300) is a Protein Coding gene. Diseases associated with EP300 include Rubinstein-Taybi Syndrome 2 and Menke-Hennekam Syndrome 2. Among its related pathways are Activated PKN1 stimulates transcription of AR (androgen receptor) regulated genes KLK2 and KLK3 and Adherens junction.
How is P300 maintained in skeletal myocytes?
levels of p300 protein are temporally maintained in ligand-enhanced skeletal myocyte development. this maintenance of p300 protein is observed at the stage of myoblast differentiation, which coincides with an increase in Akt phosphorylation.
