Ctns - cystinosin, lysosomal cystine transporter

Predicted to enable L-cystine transmembrane transporter activity and solute:proton symporter activity. Involved in L-cystine transport; negative regulation of hydrogen peroxide biosynthetic process; and positive regulation of mitochondrial membrane potential. Predicted to be located in several cellular components, including cytoplasmic vesicle; intermediate filament cytoskeleton; and lysosome. Predicted to be active in lysosomal membrane. Human ortholog(s) of this gene implicated in cystinosis. Orthologous to human CTNS (cystinosin, lysosomal cystine transporter). [provided by Alliance of Genome Resources, Apr 2022]
