'Traffic controller' protein that protects DNA discovered, and it may help kill cancer cells

Mayo Clinic researchers discovered a protein that regulates DNA during cell division, which could lead to innovative cancer therapies by enhancing DNA protection and potentially targeting cancer cells.

The protein, identified by researchers at the Mayo Clinic, plays a crucial role in DNA replication and transcription, acting as a 'traffic controller' to prevent DNA damage.
This significant discovery, published in the journal Nature, may pave the way for new treatments that specifically target cancer cells by improving DNA integrity during cell division.
The protein, known as CUL3, is vital for ensuring that DNA remains intact during the complex processes of cell division, which is critical for maintaining healthy cellular functions.

Why It Matters

This breakthrough has the potential to revolutionize cancer treatments by targeting the mechanisms that protect DNA, offering hope for more effective therapies against various cancer types. Understanding the role of proteins like CUL3 could lead to advances in precision medicine.
