Although interactions between the nuclear matrix and special regions of chromosomal DNA called matrix attachment regions (MARs) are implicated in various nuclear functions, the understanding of the regulatory mechanism of MARs is still poor. A few MAR-binding proteins (MARBP) have been isolated from some plants and animals, but not from the unicellular algae. Here, we identify a novel MAR-binding protein, namely DMBP-1, from the halotolerant alga Dunaliella salina. The cDNA of DMBP-1 is 2322-bp long and contains a 1626 bp of an open reading frame encoding a polypeptide of 542 amino acids (59 kDa). The DMBP-1 expressed in Escherichia coli specifically binds A/T-rich MAR DNA. The DMBP-1 fused to green fluorescent protein appears only inside the nuclei of Chinese hamster ovarian cells transfected with the pEGFP–MBP, indicating that the protein is located in the nuclei. The findings mentioned above may contribute to better understanding of the nuclear matrix–MAR interactions.
