The idea of giving new…

In 1980 Blobel proposed that newly made proteins are targeted to and imported into the various organelles within the cell by built-in signal sequences. The signals are short stretches of amino acids encoded by the gene specifying the protein. They can be located at either end of the protein, or somewhere internally.

In many inherited diseases, proteins are mislocalized in the cell due to errors in targeting signals and transport. One example is “primary hyperoxaluria,” a rare disease, which results in kidney stones already at an early age. A signal in the enzyme alanine:glyoxylate aminotransferase normally directs it to the peroxisome. In patients, this signal is altered…
