Human cells acquire copper primarily via the copper transporter 1 protein, hCtr1. We demonstrate that at extracellular pH 7.4 CuII is bound to the model peptide hCtr11-14via an ATCUN motif and such complexes are strong enough to collect CuII from albumin, supporting the potential physiological role of CuII binding to hCtr1.
人类细胞主要通过铜转运蛋白 1 蛋白(hCtr1)摄取铜。我们证明,在细胞外 pH 值为 7.4 时,CuII 通过 ATCUN 基序与模型肽 hCtr11-14 结合,并且这些复合物足够强,可以从白蛋白中收集 CuII,支持 CuII 与 hCtr1 结合的潜在生理作用。
