In interphase nuclei, this underlying proteinaceous structure changes its organization to occupy the entire nucleus; during interphase the structure is referred to as the matrix rather than the scaffold.

#Unit 2. Cellular Organization

The metaphase scaffold consists of a dense network of fibers. Threads of DNA emanate from the scaffold, apparently as loops of average length 30 to 90 kb.

S/MARs are constitutive (continuously bound to the matrix or scaffold), or facultative and change their interactions with the matrix depending on cell type or other conditions.

SATB1, is a protein that appears to regulate the association of MARs with the matrix in order to regulate transcription of genes in the vicinity of the MAR.
