Abstract:
Matrix attachment regions (MARs) partition the genome into functional and structural loop-domains. Here, we determined the relative matrix affinity of cloned fragments of the chicken lysozyme 5' MAR. We show that this region contains a non-curved high-affinity binding site, which is 3' followed by a strongly curved DNA sequence that exhibits weak matrix binding. DNA curvature is not a physical property required for strong matrix binding. Possible biological functions of this sequence arrangement, particularly of the strongly curved DNA, are discussed.
