Summary: Enables L-cystine transmembrane transporter activity. Involved in L-cystine transport. Located in endosome; fungal-type vacuole; and plasma membrane. Used to study several diseases, including colorectal cancer (multiple); congenital disorder of glycosylation type IIj; cystinosis; familial hyperinsulinemic hypoglycemia 7; and hypoglycemia. 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]

NP_010000.1

Protein involved in cystine transport; localizes to the vacuole, plasma membrane and endosome; similarity to human cystinosin, a H(+)-driven transporter involved in L-cystine export from lysosomes and implicated in the disease cystinosis; contains seven transmembrane domains; mutation is functionally complemented by human CTNS
