Description

Dian Ding and co-authors picture an amino acid transporter that cancers exploit in this 2026 study. Cutting methionine, a key amino acid, is a rising tactic against cancer and for longer life. The transporter LAT4 pulls that amino acid in and is overactive in many cancers.

No one knew LAT4's shape, and no blocker existed. Using cryo-microscopy, the team solved its structure, plus that of a cousin transporter. A bound phenylalanine revealed the cargo pocket. A plant compound, tubeimoside-1, blocks the transporter, and the structures show how it might work. The maps give drug hunters a foothold against a cancer supply line.
