By Hook or by Crook: Multifaceted DNA-Binding Properties of MeCP2

Two new studies reveal novel DNA-binding properties of MeCP2, mutations of which cause Rett syndrome. Baker et al. report critical roles for the AT-hook domain of MeCP2 in chromatin organization and clinical features of Rett syndrome. Mellén et al. find the methyl-CpG-binding domain of MeCP2 interacts with hydroxymethyl-CpG.
