Data (including data from studies in transgenic mice) suggest that signaling via Notch2 and Notch3 plays role in promoting cell differentiation and steroidogenesis in preovulatory granulosa cells; mechanism involves regulation of gene expression of Jag1 and Rbpj. (Notch2 = Notch2 receptor; Notch3 = Notch3 receptor; Jag1 = jagged-1 protein; Rbpj = recombining binding protein suppressor of hairless)
Macrophage maturation is controlled by Notch ligand Dll1 expressed in vascular endothelial cells of arteries and requires macrophage canonical Notch signaling via Rbpj, which simultaneously suppresses an inflammatory macrophage fate. Conversely, conditional mutant mice lacking Dll1 or Rbpj show proliferation and transient accumulation of inflammatory macrophages, which antagonizes arteriogenesis and tissue repair.
RBPJ binds and trans-activates the Il23r promoter and induces IL-23R expression and represses anti-inflammatory IL-10 production in Th17 cells.
RBP-J deficiency drastically reduced dopamine release in the striatum and caused a subtle decrease in the number of dopaminergic neurons.

The protein encoded by this gene is a transcriptional regulator important in the Notch signaling pathway. The encoded protein acts as a repressor when not bound to Notch proteins and an activator when bound to Notch proteins. It is thought to function by recruiting chromatin remodeling complexes containing histone deacetylase or histone acetylase proteins to Notch signaling pathway genes. Also, this protein can bind specifically to the recombination signal sequence of immunglobulin kappa type J segments. Several transcript variants encoding different isoforms have been found for this gene, and several pseudogenes of this gene exist on chromosome 9.
