a bZIP transcription factor which can form homodimers or heterodimers with the related proteins CEBP-beta and CEBP-gamma. Binds to the promoter and modulate the expression of the gene encoding leptin, a protein that plays an important role in body weight homeostasis. Can interact with CDK2 and CDK4, thereby inhibiting these kinases and causing growth arrest in cultured cells. Note: This description may include information from UniProtKB.
