Transcriptional regulation of HLA-A and -B: differential binding of members of the Rel and IRF families of transcription factors.

Abstract excerpt

HLA-A and -B transplantation antigens can be expressed differentially at the basal level and in response to interferons (IFNs). To determine which DNA control elements and nuclear factors are responsible for these differences, HLA-A and -B upstream regulatory regions were used in expression and mobility-shift analyses. The HLA-A enhancer was found to contain two Rel (KBF/NF-kappa B) binding motifs, while the...
