CTNS (gene)
Cystinosin only transports L-CySS while other cystine transporters will work on various amino acids. Cystine molecules accumulate and form crystals within the lysosome, impairing its function. wikipedia.org

When collecting cell lysates for a Western blot, how do I induce di-sulfide bonds? I would like to conduct a simple dimerization experiment for some protein I'm collecting from a cultured cells. My thought is, that if...
For the introduction of new cystine bonds, you will probably need to maintain an appropriate redox potential when dialyzing your cell-lysate to allow your cystine bonds to reform.

INTRODUCTION. The system X C − cystine/glutamate antiporter is a member of the family of heterodimeric amino acid transporters. System X C − is composed of a light chain, designated xCT, and the 4F2 heavy chain that traffics the heterodimer to the cell membrane []. xCT functions as a major transporter for the uptake of cystine in exchange for glutamate. xCT-mediated uptake of cystine and ...

Cystinosis
By about age two, cystine crystals may also be present in the cornea. The accumulation is caused by abnormal transport of cystine from lysosomes, resulting in a massive intra-lysosomal cystine accumulation in tissues. wikipedia.org
