Microsatellite instability regulates transcription factor binding and gene expression

Abstract excerpt

Microsatellites are tandemly repeated simple sequence DNA motifs widely prevalent in eukaryotic and prokaryotic genomes. In pathogenic bacteria, instability of these hypermutable loci through slipped-strand mispairing mediates the high-frequency reversible switching of phenotype expression, i.e., phase variation. Phase-variable expression of NadA, an outer membrane protein and adhesin of the pathogen Neisseria...
