About Enhancer

Enhancer ID: E_02_0950
Species: human
Position : chr17:42078865-42079198
Biosample name:
Experiment class : Low throughput
Enhancer type: Enhancer
Disease: --
Pubmed ID:  22383952
Enhancer experiment: PCR,ChIP,Luciferase Reporter Assay
Enhancer experiment description: Reporter assays to compare the effect of the enhancer in liver,intestine and lung cells, included data that were normalized to the reporter expression driven by the NAGS promoter. While the NAGS enhancer (4.10PromEnh) increased expression of the reporter gene by 50% in liver derived cells (Figure 2A), expression of the luciferase gene did not increase in the intestine or lung derived cells (Figure 8) suggesting that the enhancer may determine tissue specificity of NAGS expression.

About Target gene

Target gene : NAGS(AGAS,ARGA)
Strong evidence: --
Less strong evidence: ChIP,Luciferase Reporter Assay
Target gene experiment description: We subsequently confirmed that these regions function as promoter and enhancer and that the enhancer is most effective in liver cells. Avidin-agarose protein_x0002_DNA pull-down assays have been used to confirm binding of Sp1 and CREB within the NAGS promoter and Hepatic Nuclear Factor 1 (HNF-1) and NF-Y within the enhancer regions. Chromatin immunoprecipitation (ChIP) and quantitative real_x0002_time PCR have been used to independently verify that Sp1 and CREB bind to the promoter region, and HNF-1 and NF-Y bind to the enhancer region. We also used 59RACE analysis to identify multiple transcription start sites for NAGS that may be species and tissue specific.

About TF

TF name : SP1(SP1)HNF1A(HNF-1A,HNF1,HNF4A,IDDM20,LFB1,MODY3,TCF-1,TCF1)NF-Y(NF-Y)
TF experiment: ChIP,qPCR
TF experiment description: Thus,Pull-down and ChIP assays confirmed that Sp1 and CREB bind along the NAGS promoter and HNF-1 and NF-Y bind along the Enhancer.

About Function

Enhancer function : Two regions of high conservation upstream of the translation start of the NAGS gene. Reporter assays confirmed that these regions represent promoter and enhancer and that the enhancer is tissue specific.
Enhancer function experiment: Luciferase Reporter Assay
