Transcription factor that coordinates proliferation arrest and the differentiation of myeloid progenitors, adipocytes, hepatocytes, and cells of the lung and the placenta (PubMed:8367486, PubMed:11672531, PubMed:16735515, PubMed:20176812) . Binds directly to the consensus DNA sequence 5'-T[TG]NNGNAA[TG]-3' acting as an activator on distinct target genes. During early embryogenesis, plays essential and redundant functions with CEBPB (By similarity) . Essential for the transition from common myeloid progenitors (CMP) to granulocyte/monocyte progenitors (GMP) (PubMed:11672531) . Critical for the proper development of the liver and the lung (By similarity) . Necessary for terminal adipocyte differentiation, is required for postnatal maintenance of systemic energy homeostasis and lipid storage (PubMed:11672531) . To regulate these different processes at the proper moment and tissue, interplays with other transcription factors and modulators. Downregulates the expression of genes that maintain cells in an undifferentiated and proliferative state through E2F1 repression, which is critical for its ability to induce adipocyte and granulocyte terminal differentiation. Reciprocally E2F1 blocks adipocyte differentiation by binding to specific promoters and repressing CEBPA binding to its target gene promoters (PubMed:11672531) . Proliferation arrest also depends on a functional binding to SWI/SNF complex (By similarity) . In liver, regulates gluconeogenesis and lipogenesis through different mechanisms. To regulate gluconeogenesis, functionally cooperates with FOXO1 binding to IRE-controlled promoters and regulating the expression of target genes such as PCK1 or G6PC. To modulate lipogenesis, interacts and transcriptionally synergizes with SREBF1 in promoter activation of specific lipogenic target genes such as ACAS2. In adipose tissue, seems to act as FOXO1 coactivator accessing to ADIPOQ promoter through FOXO1 binding sites (By similarity) .

ELISA Kit

Enzyme-linked Immunosorbent assay-Sandwich

Colorimetric

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to CCAAT/Enhancer Binding Protein Alpha (CEBPa) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to CCAAT/Enhancer Binding Protein Alpha (CEBPa) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain CCAAT/Enhancer Binding Protein Alpha (CEBPa), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of CCAAT/Enhancer Binding Protein Alpha (CEBPa) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
