title: Methylating the DNA of the most repressed: special access required.
abstract: A new study (Zemach et al., 2013) suggests that the chromatin remodeling ATPase DDM1 is specifically required for cytosine methylation at linker histone H1-associated heterochromatin, facilitating access by three cytosine methyltransferases, including a previously uncharacterized CHH methylase, CMT2.
