Specificity / Sensitivity
C/EBPβ Antibody recognizes endogenous levels of total C/EBPβ protein. This antibody does not cross-react with C/EBPα protein.
Species Reactivity:
Human
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human C/EBPβ protein. Antibodies are purified by protein A and peptide affinity chromatography.
Background
C/EBPβ is a member of the transcription factor family of CCAAT/enhancer-binding proteins (C/EBPs) that are critical for cellular differentiation and function (1). There are various N-terminally truncated C/EBPβ isoforms: full-length C/EBPβ, C/EBPβ-LAP (liver-enriched activator protein), and C/EBPβ-LIP (liver-enriched inhibitory protein). In triple-negative breast cancer cells, aerobic glycolysis was shown to control the expression of C/EBPβ-LAP, which in turn stimulates the expression of granulocyte colony-stimulating factor (G-CSF) and granulocyte macrophage colony-stimulating factor (GM-CSF). These factors are secreted from the cancer cells to promote myeloid-derived suppressor cell (MDSC) development in the tumor microenvironment, thereby suppressing anti-tumor immunity (2). In addition, research studies showed that decreased C/EBPβ-LIP expression delays age-related phenotypes in mice, suggesting a potential role for C/EBPβ-LIP in aging (3).
