To unravel how KANK1 is recruited to the pan-cadherin+ cell-cell junctions, we searched for KANK1 interacting proteins in the human MCF7 breast cancer cell line, which expressed KANK1 at FAs and cell-cell junctions (Fig. 4a) and are non-invasive and hence, resemble primary PyMT-induced carcinoma in situ tumor cells54,55. The gene discussed is KANK1; the disease is breast cancer.
