NCIt definition : CCAAT/enhancer binding protein alpha (358 aa, 38 kD) is encoded by the human CEBPA
gene. This nuclear protein is a DNA-binding bZIP transcription factor that, as a homodimer,
recognizes common motifs in both the promoter (CCAAT sequence) and enhancer (core
homology sequence) regions of genes.;
NCIt note : CEBPA protein binds to the leptin gene promoter and modulates expression of the leptin
protein, which is important in body weight homeostasis. CEBPA protein interacts with
CDK2 and CDK4, thereby inhibiting kinase activity which results in cell growth arrest.
This protein also plays an important role in the differentiation of immature granulocytes.;
