Recombinant human RBPJL (Recombining Binding Protein Suppressor of Hairless-Like) is a protein belonging to the RBPJ (RBP-Jκ) family, which plays critical roles in transcriptional regulation. RBPJL shares structural homology with RBPJ, a key mediator of the Notch signaling pathway, but exhibits distinct functional characteristics. Unlike RBPJ, RBPJL lacks a Notch-binding domain and is not directly involved in canonical Notch signaling. Instead, it is primarily expressed in tissues such as the pancreas, where it interacts with the PTF1 (pancreas transcription factor 1) complex to regulate genes essential for exocrine pancreas development and function. Studies highlight its role in maintaining acinar cell identity and supporting digestive enzyme production.
RBPJL's ability to bind DNA and recruit chromatin-modifying complexes underscores its importance in cell-specific transcriptional programs. Recombinant RBPJL proteins are typically generated using expression systems like *E. coli* or mammalian cells for functional studies, enabling insights into its regulatory mechanisms. Its unique properties make it a valuable tool for exploring Notch-independent pathways, tissue-specific differentiation, and diseases like pancreatic cancer, where dysregulation of RBPJL-associated networks may contribute to pathology. Research on RBPJL continues to expand our understanding of developmental biology and molecular therapeutics. (Word count: 199)
