How the brain transporter NaDC3 moves key molecules and can be blocked

Transport Cycle and Inhibition of Human Na+-dicarboxylate Cotransporter NaDC3

['FUNDING_R01'] · NEW YORK UNIVERSITY SCHOOL OF MEDICINE · NIH-11259452

Researchers are looking at how the NaDC3 protein in the brain moves molecules like N-acetyl-aspartate and whether blocking it could help people with Canavan disease.

What this research studies

This project aims to map the shape and movement of the human NaDC3 transporter as it carries dicarboxylates into brain cells. The team will test how small molecules bind and block the transporter and will observe the protein switching between outward- and inward-facing states. Work uses purified human protein, structural and biochemical methods, and inhibitor testing focused on metabolites such as N-acetyl-aspartate that are linked to Canavan disease. Findings could guide the design of drugs to limit harmful metabolite buildup in the brain.

Who could benefit from this research

Good fit: People with Canavan disease or related disorders that affect N-acetyl-aspartate metabolism would be the most relevant candidates to follow this research or participate in related sample/donor efforts.

Not a fit: People with neurological conditions that do not involve N-acetyl-aspartate or the NaDC3 transporter are unlikely to receive direct benefit from this project.

Why it matters

Potential benefit: If successful, the work could point to drugs that reduce N-acetyl-aspartate overload and help protect white matter in people with Canavan disease.

How similar studies have performed: Some small-molecule inhibitors of NaDC3 and related transporter structures have been reported, but a full, detailed picture of NaDC3's transport cycle and inhibition is still emerging.
