Paving the way for potential Parkinson’s treatments

AlphaFold: Impact stories

Scientists are using AlphaFold to accelerate research in nearly every field of biology.

Over 2 million researchers in over 190 countries are using the AlphaFold Protein Structure Database to inform their research.

Explore some of their stories

From building more effective malaria vaccines to breaking down single-use plastics, AlphaFold is helping scientists accelerate research in nearly every field of biology.

It normally takes four years to identify and characterise one of these small proteins. With the help of AlphaFold we managed 23 in a few months.

Paving the way for potential Parkinson’s treatments

The symptoms of Parkinson’s develop when a person’s brain can no longer make enough of the chemical dopamine.

In around 10% of patients, this is caused by a particular genetic mutation that encodes a protein known as ‘PINK1’. PINK1 plays a key role in the breakdown and removal of mitochondria – which are often referred to as the powerhouses of our cells. If this process fails, the mitochondria build up. This eventually leads to the loss of dopamine-producing nerve cells.

Researchers have used AlphaFold to predict the structure of PINK1.
This knowledge has helped them explore what effect other mutations may have, and how those might lead to Parkinson’s. That could help pave the way for new treatments that could impact over 10 million people worldwide.
