RBPJ

Recombination signal binding protein for immunoglobulin kappa J region is a protein that in humans is encoded by the RBPJ gene.

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.

Interactions
RBPJ has been shown to interact with:
 * NOTCH1
 * NCOR2,
 * PCAF,
 * SND1,
 * SNW1,
 * SOX18, and
 * HIF1a.
