As expected, singly expressed myc-RalGDS and its truncated forms distributed in cytoplasm (data not shown), however, when co-transfected with GFP-RILP, myc-RalGDS was recruited to the RILP-labeled structures and co-localized with GFP-RILP well, indicating that RILP recruits both endogenous and exogenous RalGDS in breast cancer cells. The gene discussed is MYC; the disease is breast carcinoma.
