TMEM201 and breast carcinoma: To further explore the PPI network of RBP7 in breast cancer, we used STRING to identify genes that may interact with RBP7. The interactions between RBP7 and proteins encoded by the functional genes, including SLC45A1, SLC25A33, UBE4B, TMEM201, NMNAT1, SOCS7, SOCS4, GPR157, PIK3R3, and POLR2G, are shown in Figure 7(a).
