WebThe lysosomal transporter Cystinosin exports cystine, which is further reduced to cysteine in the cytosol. Cysteine is metabolized to coenzyme A (CoA) and fuels acetyl-CoA metabolism. Cysteine metabolism drives … WebThe major treatment for cystinosis is a cystine-depleting medication called cysteamine. Cysteamine is taken up by cells and binds to cystine within the lysosome, allowing it to escape the lysosome through a different transporter protein. This prevents cystine accumulation and crystal formation.
