About Enhancer

Enhancer ID: E_01_0421
Species: human
Position : chr1:55036580-55038580
Biosample name:
Experiment class : High+Lowthroughput
Enhancer type: Enhancer
Disease: Cancer
Pubmed ID:  29885262
Enhancer experiment: transcription,luciferase assay,Western blot,RT-qPCR,ELISA,ChIP,
Enhancer experiment description: We, therefore, studied the effect of PCSK9 on interferon (IFN) ? expression. We show that PCSK9 decreases IFN? promoter/enhancer activity, mRNA and protein levels, and its downstream 2',5'-oligoadenylate synthetase-1 mRNA level. ProPCSK9, but not the cleaved PCSK9, down-regulates IFN? promoter/enhancer activity. Moreover, PCSK9 decreases IFN? promoter/enhancer activity through the positive regulatory domain IV region where the activating transcription factor-2 (ATF-2)/c-Jun heterodimer binds. Mechanistically, we demonstrate an interaction between PCSK9 and ATF-2, which reduces ATF-2/c-Jun dimerization and ATF-2/c-Jun binding to the IFN? enhancer. This novel function of PCSK9 should have important implications in optimizing the clinical use of PCSK9 inhibitors.
