Reciprocal, methylation-dependent binding of Zfp57 and Gzf1 safeguards Dlk1-Dio3 imprinting during developmental reprogramming
Genomic imprinting secures parent-specific gene expression through differential DNA methylation at imprinted control regions (ICRs). However, how unmethylated alleles resist de novo methylation remains unclear. Using an allelic Dlk1-Dio3 ICR methylation reporter and genome-wide loss-of-function screening, we identify t...
