title: A gel retardation assay system for studying protein binding to simple repetitive DNA sequences.
abstract: Simple repetitive DNA sequences have been regarded as mere "junk" present in all eukaryotic genomes. In fact, mixed simple repeat (gt)n(ga)m sequences are present in major histocompatibility complex MHC-DRB genes for long evolutionary times, including such distant animals as artiodactyla and man. We describe herein an unsophisticated method which reveals that at least certain simple repetitive (gt)n(ga)m sequences bind nuclear proteins and show characteristics of a specific DNA-protein interaction via gel retardation.
