What chromosome is EP300?

The EP300 gene is located on the long (q) arm of the human chromosome 22 at position 13.2. This gene encodes the adenovirus E1A-associated cellular p300 transcriptional co-activator protein. EP300 is closely related to another gene, CREB binding protein, which is found on human chromosome 16.

Is BRD4 a transcription factor?

BRD4 is a transcriptional and epigenetic regulator that plays a pivotal role during embryogenesis and cancer development.

What is acetyltransferase p300?

Abstract. The transcriptional co-activator p300 is a histone acetyltransferase (HAT) that is typically recruited to transcriptional enhancers and regulates gene expression by acetylating chromatin.

Is BRD4 a kinase?

BRD4 is an atypical kinase that binds to Pol II CTD.

What does BRD4 bind to?

The double bromodomain protein Brd4 binds to acetylated chromatin during interphase and mitosis.

How does acetylation affect lysine?

Nonhistone Proteins Lysine acetylation can have wide-reaching effects. Acetylation of lysines can alter the three-dimensional structure of a protein, affecting its ability to bind other proteins or DNA. Furthermore, acetylation can have an impact on the subcellular localization, activity, and stability of a protein.

Is BRD4 an enzyme?

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….

Does BRD4 bind DNA?

BRD4-BD1 does not interact with DNA, thus, the binding affinities for histone peptides and nucleosomes are the same.

What is the function of the EP300 gene?

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 does EP300 mean?

EP300 (E1A Binding Protein P300) is a Protein Coding gene. Diseases associated with EP300 include Rubinstein-Taybi Syndrome 2 and Menke-Hennekam Syndrome 2 .

What is the function of p300 protein?

The p300 protein appears to be critical for normal development before and after birth. The p300 protein carries out its functions by turning on (activating) transcription, which is the first step in the production of protein from the instructions stored in DNA.

Is EP300 mutation associated with higher TMB and high TMB?

Among them, EP300 mutation was associated with higher TMB and indicated a favorable clinical prognosis. Furthermore, based on Gene set enrichment analysis (GSEA) and CIBERSORT algorithm, we observed that EP300 mutation upregulated signaling pathways involved in immune system and enhanced antitumor immune response.
