摘要

CCAAT/enhancer binding protein (C/EBP) ε is a recently cloned member of the C/EBP family of transcription factors and is expressed exclusively in cells of hematopoietic origin. The human C/EBP gene is transcribed by two alternative promoters, Pα and Pβ. A combination of differential splicing and alternative use of promoters gener- ates four mRNA isoforms, of 2.6 kb and 1.3-1.5 kb in size. These transcripts can encode three proteins of calculated molecular mass 32.2 kDa, 27.8 kDa, and 14.3 kDa.
