Human cells acquire copper primarily via the copper transporter 1 protein, hCtr1. We demonstrate that at extracellular pH 7.4 Cu-II is bound to the model peptide hCtr1(1-14)via an ATCUN motif and such complexes are strong enough to collect Cu-II from albumin, supporting the potential physiological role of Cu-II binding to hCtr1.
