Background InformationRE1-silencing transcription factor (UniProt: Q13127; also known as REST, Neural-restrictive silencer factor, X2 box repressor) is encoded by the REST (also known as NRSF, XBR) gene (Gene ID: 5978) in human. REST is a transcriptional repressor that acts by binding a DNA sequence element called the neuron-restrictive silencer element (NRSE). It is ubiquitously expressed, and higher expression is found in the tissues of the lymphocytic compartment, including spleen, thymus, peripheral blood lymphocytes, and ovary. It is also found in undifferentiated neuronal progenitor cells and is believed to acts as a master negative regular of neurogenesis. Expression of REST is reported to be cell cycle-dependent with reduced levels in the G2 phase. It is involved in maintaining the quiescent state of adult neural stem cells and prevents their premature differentiation into mature neurons. REST restricts the expression of neuronal genes by associating with two distinct corepressors, SIN3A and RCOR1, which in turn recruit histone deacetylase to the promoters of REST-regulated genes. REST also mediates repression by recruiting the BHC complex at RE1/NRSE sites, which acts by deacetylating and demethylating specific sites on histones and acting as a chromatin modifier. Mutations in REST gene can lead to Wilms tumors, a pediatric malignancy of the kidney that occurs due to uncontrolled multiplication of renal stem, stromal, and epithelial cells.

ApplicationAnti-REST, Cat. No. 07-579, is a rabbit polyclonal antibody that detects REST and is tested for use in Western Blotting.
Key Applications
  • Western Blotting
Application NotesUpdated information-Rest is glycosylated. From http://amsdottorato.cib.unibo.it/687/
From the summary:
"Finally, the glycosylation pattern of the REST protein was analysed, moving from the observation that the molecular weight calculated on REST sequence is about 116 kDa but using western blotting this transcription factor appears to have distinct apparent molecular weight (see Table 1.1): this difference could be explained by post-translational modifications of the proteins, like glycosylation. In fact recently, several studies underlined the importance of O-glycosylation in modulating transcriptional silencing, protein phosphorylation, protein degradation by proteasome and protein–protein interactions [Julenius et al., 2005; Zachara and Hart, 2006]. Deglycosilating analysis showed that REST protein in SH-SY5Y and HEK293 cells is Oglycosylated and not N-glycosylated. Moreover, using several combination of deglycosilating enzymes it is possible to hypothesize the presence of Gal-β(1-3)-GalNAc residues on the endogenous REST, while β(1-4)-linked galactose residues may be present on recombinant REST protein expressed in HEK293 cells. However, the O-glycosylation process produces an immense multiplicity of chemical structures and monosaccharides must be sequentially hydrolyzed by a series of exoglycosidase. Further experiments are needed to characterize all the post-translational modification of the transcription factor REST." In particular the authors show that REST migrates at 200kd in SH-SY5Y cells.

Entrez Gene Number
Entrez Gene SummaryThis 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. The protein is also found in undifferentiated neuronal progenitor cells, and it is thought that this repressor may act as a master negative regular of neurogenesis. Alternatively spliced transcript variants have been described; however, their full length nature has not been determined.
