[Role of G(-43)A polymorphism in the promoter region of the Xist gene in non-random X-chromosome inactivation in intraspecific hybrid voles].
Interaction of transcription factor CTCF with the minimal promoter of Xist gene was investigated in intraspecific hybrids ofcommon voles. CTCF was shown to bind with the minimal promoter region in vivo. However, the experiments of the delay in gel resulted in the absence of interaction between the CTCF factor and its potential binding site. Probably, G(-43)A substitution influences binding efficacy of another transcription factor such as activator protein 2, AP2.
