<jats:p>Studies of Schizosaccharomyces pombe and mammalian cells identified a series of histone modifications that result in transcriptional repression. Lysine 9 of histone H3 (H3K9) is deacetylated by the NuRD complex,methylated by a histone methyltransferase (HMT) and then bound by a chromodomain-containing protein, such as heterochromatin protein 1 (HP1),leading to transcriptional repression. A Caenorhabditis elegansNuRD-like complex and HP1 homologs regulate vulval development, but no HMT is known to act in this process.
