Mutations in MeCP2 lead to Rett syndrome. Here, MeCP2-DNA complexes have been imaged by AFM (Digital Instruments Nanoscope) in air using human MeCP2 and an 828 bp DNA sequence containing several methylated CpGs. MeCP2, which appears as bright circles in AFM images, and volume measurements of the complexes suggest that MeCP2 monomers and dimers are present and that MeCP2 binds DNA cooperatively. Other images in the linked set show looped structures and large complexes containing multiple DNA strands and MeCP2 molecules. These configurations are likely promoted by the multiple independent DNA-binding domains of MeCP2."},"ITEMTYPE":{"onto_name":"recorded image","onto_id":"FBbi:00000265"},"CELLULARCOMPONENT":{"free_text":"nucleus"},"RELATIONTOINTACTCELL":{"onto_name":"isolated subcellular component","onto_id":"FBbi:00000579"},"SOURCEOFCONTRAST":{"free_text":"specimen height"},"GROUP_ID":"7760","MOLECULARFUNCTION":{"onto_id":"GO:0016565"},"HUMAN_DISEASE":[{"onto_name":"Rett syndrome","onto_id":"DOID:1206"}],"TERMSANDCONDITIONS":{"free_text":"public_domain"},"IMAGINGMODE":[{"onto_name":"microscopy","onto_id":"FBbi:00000241"},{"onto_name":"atomic force microscopy","onto_id":"FBbi:00000259"}],"DIMENSION":[{"Space":{"Image_size":512,"Pixel_size":{"unit":"nanometers","value":1.95},"axis":"X"}},{"Space":{"Image_size":512,"Pixel_size":{"unit":"nanometers","value":1.95},"axis":"Y"}}],"NCBIORGANISMALCLASSIFICATION":{"onto_name":"Homo sapiens","onto_id":"NCBITaxon:9606"},"PREPARATION":{"onto_name":"glutaraldehyde fixed tissue","onto_id":"FBbi:00000011"},"CELLTYPE":{"free_text":"neuron"},"PATHOLOGICALPROCESS":{"onto_id":"DOID:DOID:1206"}}},"Citation":{"Title":"Shlyaktenko, Luda; Woodcock, Chris (2010) CIL:7426, Homo sapiens, neuron.
