Identification of methionine-rich clusters that regulate copper-stimulated endocytosis of the human Ctr1 copper transporter.

Abstract excerpt

Copper uptake and subsequent delivery to copper-dependent enzymes are essential for many cellular processes. However, the intracellular levels of this nutrient must be controlled because of its potential toxicity. The hCtr1 protein functions in high affinity copper uptake at the plasma membrane of human cells. Recent studies have shown that elevated copper stimulates the endocytosis and degradation of the hCtr1...
