MET1 (source code)

= MET1
{c}

A <plant> <CG methylation> maintenance <enzyme>.

Its activity helps copy a <CG methylation> pattern after <DNA replication>. Reduced <MET1> function can therefore change heritable <chromatin> states while leaving the corresponding <DNA> base order unchanged; this separates an epigenetic mark from a sequence <mutation>. <Molecular Biology of the Cell, 4th edition by Bruce Alberts and others>[Chapters 4–7, chromatin, replication and gene regulation]{ref}
