CEBPA (CCAAT enhancer binding protein alpha)

CEBPA (CCAAT enhancer binding protein alpha)

C/EBPa protein domains The basic region leucine zipper domain mediates DNA binding, homodimerization of C/EBPa and heterodimerization with other members of the C/EBP family. This region is also involved in mediating protein-protein interactions with other transcription factors involved in lineage determination and growth proliferation. N-terminal region transactivating domains mediate interacti...

CCAAT/Enhancer-Binding Protein Thrombin-Induced

CCAAT/enhancer-binding protein homologous protein (CHOP) regulates osteoblast differentiation.

Differentiation of committed osteoblasts is controlled by complex activities involving signal transduction and gene expression, and Runx2 and Osterix function as master regulators for this process. Recently, CCAAT/enhancer-binding proteins (C/EBPs) have been reported to regulate osteogenesis in addition to adipogenesis. However, the roles of C/EBP transcription factors in the control of osteobl...

Epigenetic modification of CCAAT/enhancer binding protein alpha expression in acute myeloid leukemia.

Functional loss of CCAAT/enhancer binding protein alpha (C/EBP alpha), a master regulatory transcription factor in the hematopoietic system, can result in a differentiation block in granulopoiesis and thus contribute to leukemic transformation. Here, we show the effect of epigenetic aberrations in regulating C/EBP alpha expression in acute myeloid leukemia (AML). Comprehensive DNA methylation a...

CCAAT enhancer-binding protein alpha suppresses the rat placental glutathione S-transferase gene in normal liver.

The rat placental glutathione S-transferase (GST-P), an isozyme of glutathione S-transferase, is not expressed in normal liver but is highly induced at an early stage of chemical hepatocarcinogenesis and in hepatomas. Recently, we reported that the NF-E2 p45-related factor 2 (Nrf2)/MafK heterodimer binds to GST-P enhancer 1 (GPE1), a strong enhancer of the GST-P gene, and activates this gene in...
