Transcription factors bind DNA and protein. Now, researchers in Whitehead Institute Member Richard Young’s lab find that many transcription factors can also bind RNA, which fine tunes their regulation of gene expression, suggesting new therapeutic opportunities.

How do cells decide how long to pause division after they detect errors? Whitehead Institute Member Iain Cheeseman and colleagues identified that the key player is a previously undiscovered protein that was hiding in plain sight.

A new study reveals that the protein MTCH2, which is essential in a variety of cellular processes, is responsible for shuttling various other proteins into the membrane of mitochondria. The finding could have implications for cancer treatments and provides insight into a variety of MTCH2-linked conditions.
