C/EBP Beta (CEBPB) Antibody – Rabbit Polyclonal

The protein encoded by this intronless gene is a bZIP transcription factor which can bind as a homodimer to certain DNA regulatory regions. It can also form heterodimers with the related proteins CEBP-alpha, CEBP-delta, and CEBP-gamma. The encoded protein is important in the regulation of genes involved in immune and inflammatory responses and has been shown to bind to the IL-1 response element in the IL-6 gene, as well as to regulatory regions of several acute-phase and cytokine genes. In addition, the encoded protein can bind the promoter and upstream element and stimulate the expression of the collagen type I gene. [provided by RefSeq, Jul 2008]

C/EBP-beta: a bZIP transcription factor which can form homodimers or heterodimers with the related proteins CEBP-alpha, -delta and -gamma. Involved in immune and inflammatory responses. Specifically binds to regulatory regions of genes encoding IL-6, other cytokines and several acute-phase proteins. There are two forms of C/EBPbeta, the 38kDa liver activating protein (LAP) and the 20kDa liver inhibitory protein (LIP) which may be products of alternative translation. LAP is a transcriptional activator while LIP may inhibit C/EBPbeta transcriptional activity. Phosphorylated and activated by ERK1/2.
