Specifically binds to an IL-1 response element in the IL-6 gene. NF-IL6 also binds to regulatory regions of several acute-phase and cytokines genes. It probably plays a role in the regulation of acute-phase reaction, inflammation and hemopoiesis. The consensus recognition site is 5'-T[TG]NNGNAA[TG]-3'. Functions in brown adipose tissue (BAT) differentiation (By similarity). Regulates the transcriptional induction of peroxisome proliferator-activated receptor gamma (PPARG).<ref>PMID:20829347</ref> |

| - | Three types of protein-DNA complexes, AML1/Runx-1/CBFalpha(Runt)-CBFbeta-C/EBPbeta(bZip)-DNA (CBFalpha-beta-C/EBPbeta-DNA), AML1/Runx-1/CBFalpha(Runt)-C/EBPbeta(bZip)-DNA (CBFalpha-C/EBPbeta-DNA) and AML1/Runx-1/CBFalpha(Runt)-DNA (CBFalpha-DNA), were crystallized. The crystals were all orthorhombic and belonged to space groups C222(1), P2(1)2(1)2 and P2(1)2(1)2(1), respectively. The resolutions of CBFalpha-beta-C/EBPbeta-DNA and CBFalpha-C/EBPbeta-DNA crystals were both 3 A, while that of the CBFalpha-DNA crystal was 2.65 A. Complete data sets were collected for all of the native crystals, along with MAD and MIR data sets for CBFalpha-beta-C/EBPbeta-DNA. The heavy-atom site was determined using MAD data for a gold derivative of CBFalpha-beta-C/EBPbeta-DNA. | ||
