Interactomes of neural cell adhesion molecule 1 and the metal ion transporter ZIP6 in mouse NMuMG epithelial cells with transforming growth factor beta 1-induced fibroblastoid morphology

The prion protein (PrP) evolved from the subbranch of ZIP metal ion transporters comprising ZIPs 5, 6 and 10, raising the prospect that the study of these ZIPs may reveal insights relevant for understanding PrP function. PrP and ZIP6 are required for the execution of a cellular program known as epithelial-to-mesenchymal transition (EMT). Polysialylation of neural cell adhesion molecule 1 (NCAM1) during EMT is also controlled by PrP. Here we report the ZIP6 interactome and ZIP6-dependent NCAM1 interactome in a mouse cell EMT model.
