Dr Liz Carpenter talks about her research on membrane proteins and drug development. Membrane proteins are the gateways to our cells - with nutrients, waste products, and even DNA and proteins entering and leaving cells via these tightly controlled proteins. Drugs often target membrane proteins; therefore, understanding their molecular structure helps us design better drugs. Dr Liz Carpenter uses X-ray crystallography to solve membrane protein structures. This information is then used to improve treatments for heart disease and neurological diseases.
