In a study using MCF‑7 cells, the isolated C‑terminal domain of metallothionein‑3 (MT3) was found to induce dome formation—a cellular manifestation of vectorial active transport—by increasing GAGE gene expression, whereas the presence of the N‑terminal domain suppressed this effect. In addition, transfection with metallothionein‑1E similarly up‐regulated GAGE genes, suggesting that regulation of GAGE expression by metallothionein isoforms may have unique implications in the development and progression of breast cancer."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n "}]}, {"type": "t", "text": "\n "}, {"type": "p", "children": [{"type": "t", "text": "\n At the same time, broader analyses of multidomain protein evolution have underscored the importance of accurate domain architecture predictions.
