The human genome must be packaged and organized in a functional manner
for the regulation of DNA replication and transcription. The nuclear
scaffold/matrix, consisting of structural and functional nuclear
proteins, remains after extraction of nuclei and anchors loops of DNA.
In the search for cis-elements functioning as chromatin domain
boundaries, we identified 453 nuclear scaffold attachment sites
purified by lithium-3,5-iodosalicylate extraction of HeLa nuclei across
30 Mb of the human genome studied by the ENCODE pilot project. The
scaffold attachment sites mapped predominately near expressed genes and
localized near transcription start sites and the ends of genes but not
to …
