Affinity chromatography using oligo DNA from a cis-active region (-453 / -389) of the human DSC2 promoter was used to isolate a protein from human CaCo-2 epithelial cells expressing DSC2. The protein was SDS-PAGE purified, trypsinized and analyzed by MALDI-TOF mass spectrometry. Peptide mass fingerprinting identified the protein as nucleolin, a ubiquitously expressed protein involved in gene regulation
