What is the normal function of the EP300 gene?
The EP300 gene provides instructions for making a protein called p300. This protein regulates the activity of many genes in tissues throughout the body. It plays an essential role in controlling cell growth and division and prompting cells to mature and assume specialized functions (differentiate). The p300 protein appears to be critical for normal development before and after birth.
The p300 protein carries out its function by activating transcription, the process of making a blueprint of a gene for protein production. Specifically, p300 connects transcription factors, which are proteins that start the transcription process, with the complex of proteins that carries out transcription. On the basis of this function, p300 is called a transcriptional coactivator.
Does the EP300 gene share characteristics with other genes?
The EP300 gene belongs to a family of genes called chromatin-modifying enzymes (chromatin-modifying enzymes).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
How are changes in the EP300 gene related to health conditions?
Genetics Home Reference provides information about prostate cancer, which is also associated with changes in the EP300 gene.
Where is the EP300 gene located?
Cytogenetic Location: 22q13.2
Molecular Location on chromosome 22: base pairs 41,092,610 to 41,180,077
The EP300 gene is located on the long (q) arm of chromosome 22 at position 13.2.
More precisely, the EP300 gene is located from base pair 41,092,610 to base pair 41,180,077 on chromosome 22.
