Abstract excerpt
Upstream ORFs (uORFs) are translational control elements found predominantly in transcripts of key regulatory genes. No mammalian genetic model exists to experimentally validate the physiological relevance of uORF-regulated translation initiation. We report that mice deficient for the CCAAT/enhancer-binding protein beta (C/EBPbeta) uORF initiation codon fail to initiate translation of the autoantagonistic LIP...
