Steric-Blocking ASO Mechanisms

Steric-Blocking ASO Mechanisms

An antisense oligonucleotide binds RNA and blocks access by selected molecular partners, potentially changing splicing, translation, or RNA stability without RNase H1 cleavage.

Overview

EXPLORE BY LEVEL

Some antisense strands work like a roadblock. They cover a chosen spot on RNA so the cell's machinery handles the message differently, for example by skipping an exon during splicing.

The output depends on transcript isoform, splice-site competition, binding-site occupancy, oligonucleotide chemistry, and cell delivery. A splicing change can alter protein sequence or abundance; it does not guarantee a functional rescue.
