Cells normally read a gene's message starting at a specific signal, the AUG start codon, and in a single reading frame. Some RNA messages break these rules.

What they work on

  1. Measure how much of the human genome can undergo multi-frame translation (MFT), using a new reporter system that detects protein made in several reading frames, in a genome-wide screen.
  2. Determine the RNA folding structures that let CAG repeat expansions and newly identified long non-coding RNAs (lncRNAs) be translated in multiple frames without an AUG start codon.
  3. Identify the cellular protein networks that support non-canonical multi-frame translation of candidate MFT sequences and CAG repeat expansions.
  4. Find therapeutically relevant modifiers that alter both normal and repeat-associated non-AUG (RAN) translation at the same time, using a first-of-its-kind screening strategy.

More about the research

In inherited brain diseases caused by CAG repeat expansions, where a short three-letter DNA sequence is copied too many times, cells can make several toxic proteins from the same stretch of RNA. Understanding how this rule-breaking works could point to treatments that act on many of these diseases at once.

Why it matters

People with CAG repeat expansion diseases currently have few options, and each disease is usually treated separately. By identifying the RNA structures, proteins and modifiers that control multi-frame translation, this work could reveal therapy targets that work across several CAG repeat disorders. The same targets might apply to a wider range of neurological diseases.
