C/EBP are DNA-binding proteins that recognize two different motifs: the CCAAT homology common to many promoters and the enhanced core homology common to many enhancers.
Interacting selectively and non-covalently with DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.

Sequence-specific DNA binding transcription factor activitydefinition[GO:0003700]‹silver
Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex.
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lipopolysaccharide stimulus; lipopolysaccharide is a major component of the cell wall of gram-negative bacteria.
The chemical reactions and pathways resulting in the formation of cytokines, any of a group of proteins that function to control the survival, growth and differentiation of tissues and cells, and which have autocrine and paracrine activity.
Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.
Members of the CsolidusEBP family of transcriptional factors have been implicated in the regulation of genes in a variety of tissues. We report here the isolation and characterization of the human C/EBPepsilon gene (CEBPE). By using low-stringency hybridization conditions and probes derived from the C/EBPalpha and C/EBPdelta genes, we have isolated overlapping genomic clones that cover almost 25 kb of the C/EBPepsilon gene locus and corresponding cDNA clones. DNA sequence analysis reveals that the gene encodes a protein highly homologous to rat CRP1. The gene was assigned to chromosome 14q11.2 by fluorescence in situ hybridization and was physically linked to the genetic marker D14S990. Based on linkage data derived from this marker, we positioned the CEBPE gene between the T-cell receptor alpha/delta locus and a cluster of four serine proteases expressed exclusively in hematopoietic cells. Expression of C/EBPepsilon was detected in Jurkat T-cell and in HL 60 promyelocytic cell lines. From a variety of normal human tissues studied, expression of mRNA was monitored only in peripheral blood mononuclear cells, tissues involved in the immune system, and ovaries. These data demonstrate that the C/EBPepsilon gene shows a restricted pattern of expression, has an intriguing chromosomal location, and suggest a possible role for the regulation of certain genes in cells of myeloid and lymphoid lineages.
An endocytosis process that results in the engulfment of external particulate material by phagocytes. The particles are initially contained within phagocytic vacuoles (phagosomes), which then fuse with primary lysosomes to effect digestion of the particles.
Protein involved in the transfer of genetic information from DNA to messenger RNA (mRNA) by DNA-directed RNA polymerase. In the case of some RNA viruses, protein involved in the transfer of genetic information from RNA to messenger RNA (mRNA) by RNA-directed RNA polymerase.
A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
