EP300 Gene

What is the EP300 gene?

EP300 encodes e1a binding protein p300, a protein involved in histone acetyltransferase / transcriptional coactivator. It belongs to the Epigenetics category and is part of the Methylation & Neurotransmitters biological cluster. EP300 encodes p300, a histone acetyltransferase and transcriptional coactivator that activates gene expression by acetylating histones and transcription factors.

Biological role and pathway

EP300 is involved in the histone acetyltransferase / transcriptional coactivator pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Methylation & Neurotransmitters cluster work together to maintain balanced function across interconnected biological systems.

Variants in genes within this pathway may influence an individual's predisposition to altered function in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

Known genetic variants

The following variants (SNPs) in the EP300 gene have been studied in relation to epigenetics and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.
