SATB1

SATB homeobox 1, also known as SATB1, is a human gene.

SATB1, the global chromatin organizer and transcription factor, has emerged as a key factor integrating higher-order chromatin architecture with gene regulation. Recent studies have unraveled the role of SATB1 in organization of chromatin 'loopscape' and its dynamic nature in response to physiological stimuli. At genome-wide level, SATB1 seems to play a role in organization of the transcriptionally poised chromatin. SATB1 organizes the MHC class-I locus into distinct chromatin loops by tethering MARs to nuclear matrix at fixed distances. Silencing of SATB1 mimics the effects of IFNgamma treatment on chromatin loop architecture of the MHC class-I locus and altered expression of genes within the locus.
