Within the set of differential protein assemblies exhibiting rewiring in the breast adenocarcinoma-derived MDA-MB-231 cells, we enriched a well-characterized multiprotein assembly involving Src, PTK2 (FAK) and PXN, corroborating previously reported molecular mechanisms underlying breast tumor plasticity34,35 (Fig. 3d). This evidence concerns the gene PXN and breast adenocarcinoma.
