What is the role of cohesins at the IFNG locus?
Cohesins form cell-type-specific long-range chromosomal cis-interactions at the developmentally regulated IFNG locus. Hence, the ability of cohesin to constrain chromosome topology is used not only for the purpose of sister chromatid cohesion, but also to dynamically define the spatial conformation of specific loci. This new aspect of cohesin function is probably important for normal development and disease.
