Aroian et al., 1990) (Wormbase WS2). Recently we described a role for LET-23 in e regulation of C. elegans behavior (Van Buskirk and Sternberg, 2007). e me ylation of H3K36 might also recruit e C. elegans NuA4-like complex, which contains class C synMuv proteins (Ceol et al., 2006), to inhibit inappropriate transcriptional initiation of lin-3. Consistent wi is model, H3K9 trime ylation and HP1γ have recently been found to be enriched in actively transcribed genes in human cells. e Caenorhabditis elegans heterochronic genes control e relative timing and sequence of many events during postembryonic development, including e terminal differentiation of e lateral hypodermis, which occurs during e final (four) molt.
