Among the genes interacting with ARID1A, RAB11FIP1 is overexpressed in breast cancer (67) RAB11FIP is involved in the Rab-11 mediated vesicle recycling, endosomal trafficking and transport between the recycling endosome and the trans-Golgi network, including the trafficking of integrin α5β1, required for cancer cell invasion, metastasis, and resistance to anticancer drugs. The gene discussed is ARID1A; the disease is breast cancer.
