The histone code hypothesis posits that distinct combinations of histone modifications can recruit chromatin-modifying enzymes and exert epigenetic control over heterochromatin assembly. In the March 15 ScienceXpress, Nakayama et al. describe a role for histone methylation in heterochromatin assembly in the fission yeast Schizosaccharomyces pombe. The Clr4 protein methylated lysine 9 of histone H3 (H3Lys9) preferentially within heterochromatin-associated regions. H3Lys9 methylation led to the r

In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.
Histone Methylation is Making its Mark

Data derived from the Science Watch/Hot Papers database and the Web of Science (ISI, Philadelphia) show that Hot Papers are cited 50 to 100 times more often than the average paper of the same type and age. M. Lachner et al., "Methylation of histone H3 lysine 9 creates a binding site for HP1 proteins," Nature, 410:116-20, 2001. (Cited in 202 papers) A.J. Bannister et al., "Selective recognition of methylated lysine 9 on histone H3 by the HP1 chromo domain," Nature, 410:120-4, 2001. (Cited in 2

Researchers Focus on Histone Code
Brendan Maher | Sep 16, 2001 | 4 min read
Histones, the proteins around which DNA coils to form chromatin, are moving toward the forefront of epigenetic research (see also, "The Meaning of Epigenetics"). A recently floated hypothesis states that the highly modifiable amino termini, or tails, of these proteins could carry their own combinatorial codes or signatures to help control phenotype, and that parts of this code may be heritable. Histones are perhaps more intimately linked with DNA than any other protein. Transcriptional regulati
