Ep300 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
EP300 (E1A-associated protein p300) encodes a transcriptional coactivator and histone acetyltransferase (HAT) that plays crucial roles in gene expression, chromatin remodeling, and cellular differentiation. It is essential for learning, memory, and neuronal plasticity. [1]
The EP300 gene encodes the p300 protein, a member of the p300/CBP (CREB-binding protein) family of transcriptional coactivators. p300 functions as a molecular scaffold, bridging transcription factors with the basal transcription machinery and modifying chromatin through its histone acetyltransferase activity. Mutations in EP300 are associated with Rubinstein-Taybi syndrome and contribute to neurodegeneration. [2]
