Position-effect protection and enhancer blocking by the chicken β-globin insulator are separable activities
The 1.2-kb DNA sequence element (5′HS4) at the 5′ end of the chicken β-globin locus has the two defining properties of an insulator: it prevents an “external” enhancer from acting on a promoter when placed between them (“enhancer blocking”) and acts as a barrier to chromosomal position effect (CPE)...
