CCAAT/enhancer-binding protein gamma (C/EBPγ) is a protein that in humans is encoded by the CEBPG gene.[5][6] This gene has no introns.

The C/EBP family of transcription factors regulates viral and cellular CCAAT/enhancer element-mediated transcription. C/EBP proteins contain the bZIP region, which is characterized by two motifs in the C-terminal half of the protein: a basic region involved in DNA binding and a leucine zipper motif involved in dimerization. The C/EBP family consist of several related proteins, C/EBPα, C/EBPβ, C/EBPγ, C/EBPδ, C/EBPζ, and C/EBPε, that form homodimers and that form heterodimers with each other. CCAAT/enhancer binding protein gamma may cooperate with Fos to bind the positive regulatory element-I (PRE-I) enhancer elements.[6][7]
C/EBPγ forms heterodimer with ATF4 for transcriptional activation of target genes in autophagy specifically to amino acid starvation.[8]
C/EBPγ along with its regulator, the trauma-induced transcription factor EGR1, plays an important role in the development of chronic pain and mechanical hypersensitivity after some types of injury or surgery.[9]
