Genomic DNA encompasses several levels of organization, the nuclear matrix mediates the formation of DNA loop domains that are anchored to matrix attachment regions (MARs). By means of specific interaction with MAR binding proteins (MARBPs), MAR plays an important regulation role in enhancing transgene expression, decreasing expression variation among individuals of different transformants and serving as the replication origin. Through these years, some MARBPs have been identified and characterized from humans, plants, animals and algae so far and the list is growing. Most of MARBPs exist in a co-repressor/co-activator complex and involve in chromosome folding, regulation of gene expression, influencing cell development and inducing cell apoptosis. This review covers recent advances that have contributed to our understanding of MARBPs.
