Transcriptional activator (PubMed:26019275). 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. Required for the promyelocyte-myelocyte transition in myeloid differentiation (PubMed:10359588). Binds DNA as a homodimer and as a heterodimer (PubMed:26019275). Can form stable heterodimers with CEBPA, CEBPB and CEBPD (By similarity). Interacts with GATA1 AND SPI1 (PubMed:26019275). Interacts with SMARCD2 (PubMed:28369036). Strongest expression occurs in promyelocyte and late-myeloblast-like cell lines. Phosphorylated. The disease is caused by variants affecting the gene represented in this entry. Belongs to the bZIP family. C/EBP subfamily. CEBPE mutation db
