RE1-Silencing Transcription factor (REST), also known as Neuron-Restrictive Silencer Factor (NRSF), is a protein which in humans is encoded by the REST gene.[1][2][3]

Contents

Function

This gene encodes a transcriptional repressor which represses neuronal genes in non-neuronal tissues. It is a member of the Kruppel-type zinc finger transcription factor family. It represses transcription by binding a DNA sequence element called the neuron-restrictive silencer element (NRSE, also known as RE1). The protein is also found in undifferentiated neuronal progenitor cells, and it is thought that this repressor may act as a master negative regulator of neurogenesis. Alternatively spliced transcript variants have been described; however, their full length nature has not been determined.[1]

REST contains 8 Cys2His2 zinc fingers and mediates gene repression by recruiting several chromatin-modifying enzymes.[4]

When expressed in fruit flies, this gene results in gonads where the wings should be.

NRSF bound to DNA and cofactors on each of its two cofactor binding domains.  
Chromatin remodeling occurs, causing the gene to be 'turned off'.  

Interactions

RE1-silencing transcription factor has been shown to interact with RCOR1.[5]
