Fig. 4From: Rett syndrome – biological pathways leading from MECP2 to disorder phenotypesPathway of cytosine methylation. 5MeCyt is converted to 5OHMeCyt and further to 5-formylcytosine and 5-carboxycytosine by the TET1-3 complex. MECP2 binding to these sites prevents them from being converted. The biological process is available at wikipathways.org/instance/WP3585Back to article page
