Purification and identification of the protein binding to the 7-bp region of the IFITM3 promoter. (A) Proteins purified from the SW-13 nuclear extracts by DNA affinity chromatography using the wild-type (Fig. 1B, WT) and mutant probes (Fig. 1B, M) were resolved by SDS-PAGE and stained with silver nitrate. The 50-kDa band (arrow) was excised from the gel and analyzed by MALDI-TOF mass spectrometry. (B) The six peptides that were identified by MALDI-TOF MS and their positions in the TEF-1 protein.
