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.
