Cystine/glutamate transporter is an antiporter that in humans is encoded by the SLC7A11 gene.[1][2][3]


SLC7A11 is a member of a heteromeric Na(+)-independent anionic amino acid transport system highly specific for cystine and glutamate. In this system, designated system Xc(-), the anionic form of cystine is transported in exchange for glutamate.[supplied by OMIM][3] SLC7A11 has also been termed 'xCT', especially in older literature.

Clinical significance

Recently, SLC7A11 has been shown to be involved in the cellular import of dimethylarsino-cysteine, an active metabolite of darinaparsin, an arsenic-based glutathion S-conjugate, in cancer cells.[4]
