Thymine 120-127 activation induced cytidine deaminase Homo sapiens 45-73 22798497-3 2012 This is based in part on reported ability of activation-induced deaminase (AID) to deaminate 5-methylcytosines (5mC) to thymine. Thymine 120-127 activation induced cytidine deaminase Homo sapiens 75-78 19659441-4 2009 Evidence suggests that active DNA demethylation in mammalian cells is also mediated at least in part by a base excision repair pathway where the AID/Apobec family of deaminases convert 5-methylcytosine to thymine followed by G/T mismatch repair by the DNA glycosylase MBD4 or TDG. Thymine 205-212 activation induced cytidine deaminase Homo sapiens 145-148 15448152-3 2004 Here we show that Aid and Apobec1 are 5-methylcytosine deaminases resulting in a thymine base opposite a guanine. Thymine 81-88 activation induced cytidine deaminase Homo sapiens 18-21
