该基因编码一种跨膜蛋白，在铜跨膜转运中发挥作用。这种蛋白质定位于反式高尔基体网络，在那里它被预测在分泌途径中向铜依赖的酶供应铜。在细胞外铜升高的条件下，它重新定位到质膜上，并在铜从细胞流出的过程中发挥作用。该基因突变与门克斯病、X连锁的远端脊髓性肌萎缩和枕角综合征有关。另外还观察到了剪接的转录变体。[由RefSeq提供，2013年8月]
This gene encodes a transmembrane protein that functions in copper transport across membranes. This protein is localized to the trans Golgi network, where it is predicted to supply copper to copper-dependent enzymes in the secretory pathway. It relocalizes to the plasma membrane under conditions of elevated extracellular copper, and functions in the efflux of copper from cells. Mutations in this gene are associated with Menkes disease, X-linked distal spinal muscular atrophy, and occipital horn syndrome. Alternatively-spliced transcript variants have been observed.
