Special AT-rich sequence-binding protein 1 (SATB1) is a global chromatin organizer and nuclear transcription factor which integrates higher-order chromatin architecture with gene regulation (1). SATB1 specifically binds to nuclear matrix/scaffold-associating DNAs (MARs/SARs), which is made of AT-rich DNA sequences with one strand consisting of ATC sequences. Studies have shown that in cooperation with promyelocytic leukemia protein (PML), SATB1 and PML function as a regulatory complex which controls transcription through restructuring dynamic chromatin-loop architecture. SATB1 interacts with PML to organize the MHC class-I locus into distinct higher-order chromatin loops by anchoring MARs to nuclear matrix at fixed distances (2). As a key player in the immune system, SATB1 has been linked to regulating gene expression during the differentiation and activation of T cells. In cancer, SATB1 has been shown to reprogram chromatin organization and the transcription profiles of breast tumors to promote growth and metastasis (3).
