RBPJ also known as CBF1, is the human homolog for the Drosophila gene Suppressor of Hairless. Its promoter region is classically used to demonstrate Notch1 signaling. RBPJ has been shown to interact with: This article incorporates text from the United States National Library of Medicine, which is in the public domain.
