When we look at the structural design, it is fascinating how peptides can be covalently attached to oligonucleotides to create a unified system. These are typically hybrid molecules composed of a peptide linked to a single stranded oligo via a heterobifunctional linker. Whether the conjugation occurs at the 3' or 5' end, or even at the base of the sugar unit, the structural integrity of the final construct is paramount for its performance in experimental models.
The Mechanism of Innovation
One of the reasons I find these compounds so compelling is the intelligent navigation + precise therapy potential they offer. By utilizing Cell-Penetrating Peptides (CPPs), researchers are synthesizing CPP-ASO conjugates that demonstrate how peptides can facilitate the transport of genetic material.
I have noted that these constructs can be produced with nearly any combination of nucleic acid and peptide type, allowing for incredible customization.
