According to the above network analysis, RPL7, a tumor-derived Igλ-interacting protein, interacts with the following proteins: RPL35, RPS9, RPS12, RPL19, RPS2, RPL8, RPL4, RPS3, RPS7, RPS16, RPL18A, EEF2, RPL13, RPL15, RPS23, RPL38, RPS27A, RPS11, RPS15A, and RPLP2 (Fig. 8A). Here, RPL18A is linked to neoplasm.
