What does EGR 1 do?
EGR-1 is an important transcription factor in memory formation. It has an essential role in brain neuron epigenetic reprogramming. EGR-1 recruits the TET1 protein that initiates a pathway of DNA demethylation. Removing DNA methylation marks allows the activation of downstream genes.
What is EGR1 gene?
EGR1 (Early Growth Response 1) is a Protein Coding gene. Diseases associated with EGR1 include Ischemia and Fraser Syndrome 2. Among its related pathways are AGE-RAGE signaling pathway in diabetic complications and Angiopoietin Like Protein 8 Regulatory Pathway. An important paralog of this gene is EGR2.
Do promoters increase gene expression?
When an increase in gene expression is caused by an increase in the rate of promoter on-switching (burst frequency), noise (σ2/μ2) decreases monotonically with expression [12].
Where is ATF3 protein produced?
the nucleus
ATF3 proteins are localized in the nucleus. ATF3 is a member of the CREB/ATF family of transcription factors and both homodimerize and heterodimerize with other members of CREB/ATF family, including C/EBPg, CHOP/DDIT3, ATF2, Jun, JunB, p21SNFT/JDP1, and Nrf2/NFE2L2.
What does C FOS stand for?
C-fos is a proto-oncogene that is expressed within some neurons following depolarization. The protein product, c-fos protein, can be identified by immunohistochemical techniques. Therefore, c-fos expression might be used as a marker for neuronal activity throughout the neuraxis following peripheral stimulation.
What does Arc protein do?
Activity-regulated cytoskeleton-associated protein is a plasticity protein that in humans is encoded by the ARC gene. Arc protein is widely considered to be important in neurobiology because of its activity regulation, localization, and utility as a marker for plastic changes in the brain.
How long is a promoter?
about 100-1000 base pairs
Promoters are about 100-1000 base pairs long and are adjacent and typically upstream (5′) of the sense or coding strand of the transcribed gene. The coding strand is the DNA strand that encodes codons and whose sequence corresponds to the mRNA transcript produced.
What is the difference between promoter and enhancer?
An enhancer is a sequence of DNA that functions to enhance transcription. A promoter is a sequence of DNA that initiates the process of transcription. A promoter has to be close to the gene that is being transcribed while an enhancer does not need to be close to the gene of interest.
What activates ATF3?
for example, found that ATF3 is induced by proinflammatory cytokines, glucose, and palmitate in ß cells (25). ATF3 induction is partially mediated by the NF-κB and JNK/stress-activated protein kinase (SAPK) signaling pathways, which are two stress-induced pathways involved in diabetes.
What type of compound is ATF5?
ATF5 (Activating Transcription Factor 5) is a Protein Coding gene.
Why is c-Fos used as a marker?
C-fos is a proto-oncogene that is expressed within some neurons following depolarization. Therefore, c-fos expression might be used as a marker for neuronal activity throughout the neuraxis following peripheral stimulation.
Where is c-Fos found?
In the fields of molecular biology and genetics, c-Fos is a proto-oncogene that is the human homolog of the retroviral oncogene v-fos….c-Fos.

What kind of protein is the egr1 gene?
EGR-1 (Early growth response protein 1) also known as Zif268 (zinc finger protein 225) or NGFI-A (nerve growth factor-induced protein A) is a protein that in humans is encoded by the EGR1 gene .
How does early growth response 1 ( EGR-1 ) work?
Review of the physiology of early growth response 1 (EGR-1) in signal pathways of cancer, tumor cell proliferation, apoptosis, migration, invasion and tumor microenvironment. rs653765 G–>A variants functionally modulate ADAM10 promoter activity by altering the binding of the EGR1 transcription factor to the ADAM10 promoter.
How does EGR-1 contribute to DNA demethylation?
EGR-1 recruits the TET1 protein that initiates a pathway of DNA demethylation. Removing DNA methylation marks allows the activation of downstream genes. EGR-1, together with TET1, is employed in programming the distribution of methtylation sites on brain DNA during brain development, in learning and in long-term neuronal plasticity .
Is the egr1 gene a target of glucocorticoid action?
Transcriptome and siRNA analyses revealed that the EGR1 gene is one target of glucocorticoid action. Transcription of the EGR1 gene is activated by the RAF-MEK-ERK MAPK pathway and acts as a sensor of hyper-mitogenic pathway activity.
