Background：

Important transcription factor regulating the expression of genes involved in immune and inflammatory responses (PubMed:1741402， PubMed:9374525， PubMed:12048245， PubMed:18647749). Plays also a significant role in adipogenesis， as well as in the gluconeogenic pathway， liver regeneration， and hematopoiesis. The consensus recognition site is 5’-T[TG]NNGNAA[TG]-3’. Its functional capacity is governed by protein interactions and post-translational protein modifications. During early embryogenesis， plays essential and redundant functions with CEBPA. Has a promitotic effect on many cell types such as hepatocytes and adipocytes but has an antiproliferative effect on T-cells by repressing MYC expression， facilitating differentiation along the T-helper 2 lineage. Binds to regulatory regions of several acute-phase and cytokines genes and plays a role in the regulation of acute-phase reaction and inflammation. Plays also a role in intracellular bacteria killing (By similarity). During adipogenesis，
