Small molecules to replace sirna
Webb21 jan. 2024 · Only a very small proportion of the administrated siRNA remains available for the target cells or tissues. However, this small percentage of siRNA is easily degraded by nuclease widely distributed in vivo. Moreover, the siRNA alone cannot efficiently penetrate the cellular membrane. WebbThe protein shown here (PDB entry 1r9f ) is a suppressor protein made by tomato bushy stunt virus. It binds to siRNA and blocks its use for destruction of viral messenger RNA. Notice how the protein (in blue) acts like a ruler, stacking on each end of the siRNA (in orange and red). In this way, it seeks out and blocks only small pieces of RNA ...
