About Enhancer

Enhancer ID: E_02_0971
Species: human
Position : chr7:103823354-103846754
Biosample name:
Experiment class : Low throughput
Enhancer type: Enhancer
Disease: Haploinsufficiency
Pubmed ID:  21454523
Enhancer experiment: ChIP,qRT-PCR,3C
Enhancer experiment description: The presence of the cohesin holo-complex was confirmed by ChIP using antibodies specific for SMC1 and SA1.Most notably, HS2 functions as an enhancer, and the outer HS5 functions as an insulator. B, adult ?-globin gene induction following DMSO treatment. End point RT-PCR of ?-major gene induction and q-RT-PCR analysis of ?-major and ?-minor genes in comparison to GAPDH were examined over 4 days of DMSO treatment. Q-RT-PCR values were normalized to ribonuclease/angiogenin inhibitor 1 (rnh1).

About Target gene

Target gene : Hbb-y(Ey,Hby)
Strong evidence: 3C
Less strong evidence: ChIP
Target gene experiment description: 3C and ChIP-loop analysis of the HS2 and ?-major promoter interaction at 4 days after DMSO treatment. The interactions of a region containing HS4 and HS5 (HS4/5) with either 3?HS1 or HS-62 are compared.

About TF

TF name : Nipbl(Idn3)Ctcf(MRD21)Nfe2(NF-E2,p45)
TF experiment: ChIP
TF experiment description: Differentiation-induced Cohesin and Nipbl Binding at the ?-globin Locus Is Associated with LCR Enhancer-globin Gene Interactions.,ChIP analysis of cohesin (Rad21),Nipbl,CTCF, and NF-E2 binding to the ?-globin locus.

About Function

Enhancer function : Nipped-B-like (Nipbl) bind to the locus control region (LCR) at the CTCF insulator and distal enhancer regions as well as at the specific target globin gene that undergoes activation upon differentiation
Enhancer function experiment: ChIP,3C,PCR
Enhancer function
experiment description:
The results indicate that cohesin binds to these regions when they interact. Taken together, cohesin and Nipbl are recruited not only to the HS5 insulator, but also to the Enhancer and the active _x005f_x0001_-globin gene regions. This correlates with the induction of the interaction of these domains and ?-globin gene activation.
