The PADRE peptide (Pan-DR epitope) is defined by the specific amino acid sequence AKFVAAWTLKAAA. When investigating why this construct is so highly regarded, it becomes clear that its design is intentional. It acts as a universal synthetic peptide binding (MHC)-II receptors, specifically targeting H by H Ghaffari-Nazari·2015·Cited by 193—PADRE is a universal synthetic 13 amino acid peptidethat activates CD4+ T cells [29]. Because PADRE binds with high affinity to 15 of the 16 Read more uman Leukocyte Antigen (HLA)-DR receptors. By staying at the forefront of advancements in immunotherapy and vaccine development, researchers have utilized this sequence to create a bridge between various molecular components.
From my own review of the available literature, it is evident that the Pan-DR epitopes (PADRE) peptides were developed by optimizing polyalanine-based frameworks. This optimization allows the peptide to bind with high affinity to the majority of common human HLA-DR molecules, making it a versatile tool for laboratory assays and structural studies.
Applications and Research Context
One of the most compelling aspects of this molecule is its role as a pan DR binding peptide. Because PADRE peptide is a universal peptidic epitope, it has been integrated into various experimental designs to enhance the stability or reactivity of other molecular constructs.
