Caprin-1 protein interacts with lnc-Ma301. A Scheme of the RNA pull-down assay to identify proteins interacting with lnc-Ma301. a Both sense and antisense probes of lnc-Ma301 were verified by electrophoresis. b The pulled-down proteins by both sense and antisense probes of lnc-Ma-301 were analyzed by ESI-FT-ICR-MS. Differentially expressed proteins were those pulled down by the sense probe but not the antisense probe. c, A specific peptide was used to identify caprin-1 protein. B Caprin-1 protein was probed further as a potential interactor with lnc-Ma301, and its antibody was used to perform the RIP-qPCR to confirm their interaction
