Extra Details:: A DNA-binding protein implicated in transcriptional repression and chromosome organization and compaction. Binds nucleation sites in AT-rich DNA and bridges them, forming higher-order nucleoprotein complexes and condensing the chromosome. As many horizontally transferred genes are AT-rich, it plays a central role in silencing foreign genes. A subset of genes are repressed by H-NS in association with other proteins. Source: Recombinant protein corresponding to aa2-135 from SerRatia marcescens DNA-binding protein H-NS, fused to 6X His-Tag at N-terminal, expressed in E.coli.
