  • Relevance

    The CoREST3 gene encodes a functional corepressor required for regulation of neural specific gene expression. REST (RE1 silencing transcription factor 1) can mediate extraneuronal restriction by imposing either active repression via histone deacetylase recruitment or long term gene silencing using a distinct functional complex. Silencing of neuronal specific genes requires the recruitment of an associated corepressor, CoREST, that serves as a functional molecular beacon for the recruitment of molecular machinery that imposes silencing across a chromosomal interval, including transcriptional units that do not themselves contain REST response elements.
