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. Note: This description may include information from UniProtKB.
