In an analysis of a 90‐kb region around the human beta‐globin gene complex we have identified at least eight sites of attachment to the nuclear scaffold (SARs). While these have many potential functions, there appears to be a particular association with sequences important in the regulation of the complex. Two SARs are close to the known enhancer‐like elements of the beta‐globin gene. SARs flanking the complex co‐habit with the boundaries of the putative beta‐like globin gene regulatory domain. In contrast, we have detected no SARs within a 140‐kb region of the human alpha‐globin gene complex. If SARs play a role in the regulation of gene expression then this structural difference would imply a difference in the regulation of the two complexes.
