• Subunit: Binds DNA as a homodimer and as a heterodimer (PubMed:11018027, PubMed:11257229, PubMed:11792321). Interacts with ATF4. Binds DNA as a heterodimer with ATF4 (PubMed:11018027). Interacts with MYB; within the complex, MYB and CEBPB bind to different promoter regions (PubMed:11792321). Can form stable heterodimers with CEBPD (PubMed:1741402). Can form stable heterodimers with CEBPA and CEBPE (By similarity). Isoform 2 and isoform 3 also form heterodimers. Interacts with TRIM28 and PTGES2. Interacts with PRDM16. Interacts with CCDC85B. Forms a complex with THOC5. Interacts with ZNF638; this interaction increases transcriptional activation. Interacts with CIDEA and CIDEC; these interactions increase transcriptional activation of a subset of CEBPB downstream target genes (By similarity). Interacts with DDIT3/CHOP (PubMed:20829347). Interacts with EP300; recruits EP300 to chromatin. Interacts with RORA; the interaction disrupts interaction with EP300. Interacts (not methylated) with MED23, MED26, SMARCA2, SMARCB1 and SMARCC1 (PubMed:20111005). Interacts with KAT2A and KAT2B (By similarity). Interacts with ATF5; EP300 is required for ATF5 and CEBPB interaction and DNA binding.
• Entry Function: Isoform 3: Acts as a dominant negative through heterodimerization with isoform 2 (PubMed:11741938). Promotes osteoblast differentiation and osteoclastogenesis.
• Preparation and Storage: Store at -20 degree C. Avoid repeated freezing and thawing.

NCBI Description

This intronless gene encodes a transcription factor that contains a basic leucine zipper (bZIP) domain. The encoded protein functions as a homodimer but can also form heterodimers with CCAAT/enhancer-binding proteins alpha, delta, and gamma. Activity of this protein is important in the regulation of genes involved in immune and inflammatory responses, among other processes. The use of alternative in-frame AUG start codons results in multiple protein isoforms, each with distinct biological functions. [provided by RefSeq, Oct 2013]

Uniprot Description

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.
