 CEBPB is capable of increasing the expression of several target genes.Among them, some have specific role in the nervous system such as the preprotachykinin-1 gene, giving rise to substance P and neurokinin A and the choline acetyltransferase responsible for the biosynthesis of the important neurotransmitter acetylcholine.Other targets include genes coding for cytokines such as IL-6, IL-4, IL-5, and TNF-alpha.
