Mass spectrometry analysis of FLAG-5MP complexes


ABSTRACT: FLAG-tagged 5MP (h5MP1/BZW2 from human and 5MP/Kra from fly) was ectopically expressed in relevant host cells (HEK293T for human and S2 for fly) by transient transfection, and one-step affinity-purified by anti-FLAG affinity resin.The one-step affinity purification products were resolved by SDS-PAGE, silver-stained and subjected for MS after dividing the whole lane into 12-15 fractions.

eIF5-mimic protein (5MP) is a translational regulatory protein that binds the small ribosomal subunit and modulates its activity. 5MP is proposed to reprogram non-AUG translation rates for oncogenes in cancer, but its role in controlling non-AUG initiated synthesis of deleterious repeat-peptide products, such as FMRpolyG observed in fragile-X-associated tremor ataxia syndrome (FXTAS), is unknown. Here, we show that 5MP can suppress both general and repeat-associated non-AUG (RAN) translation by  ...[more]
