Recombination Signal Binding Protein for Immunoglobulin kappa J region (RBPJ), also known as CBF1 or CSL, is a highly conserved DNA-binding protein that serves as a central mediator in the Notch signaling pathway. It functions as a transcriptional regulator, interacting directly with the intracellular domain of activated Notch receptors to form a transcriptionally active complex. This complex drives the expression of target genes involved in cell differentiation, proliferation, and survival. In the absence of Notch activation, RBPJ typically represses transcription by recruiting corepressors like SHARP and histone deacetylases (HDACs), maintaining target genes in a silenced state.
RBPJ plays critical roles in embryonic development, hematopoiesis, and neurogenesis. Dysregulation of RBPJ-associated signaling is linked to cancers, cardiovascular diseases, and developmental disorders. Its structure includes an N-terminal domain (NTD), a beta-trefoil DNA-binding domain, and a C-terminal domain (CTD) that facilitates protein-protein interactions. Recombinant RBPJ proteins are widely used in vitro to study Notch pathway mechanisms, protein-DNA/cofactor interactions, and therapeutic targeting. Research on RBPJ continues to uncover its context-dependent functions, highlighting its dual role as both a transcriptional activator and repressor depending on cellular signals.
