  sub:_4 prov:value "cis-regulatory element located at nt +1614-1621 (5'-TGACGCAA-3') is responsible for activation of the C/EBPbeta gene. Electrophoresis mobility shift analysis revealed that proteins are bound to this element and that the amount of binding is increased following glucose deprivation. This element is homologous to a previously reported mammalian unfolded protein response element that binds XBP-1. Consistent with those data, overexpression of XBP-1 caused an increase in transcription that was mediated by the C/EBPbeta mammalian unfolded protein response element." ;
