The Drosophila SET domain encoding gene dEset is essential for proper development.

摘要
We have identified dEset, the fly homolog of human SETDB1 and mouse ESET histone lysine methyltransferases (HKMTases) that methylates the lysine 9 residue of histone 3 (H3-K9) and negatively regulates transcription of target genes. By using spatio-temporal RNA interference we show that dEset is required at several stages of development coinciding with ecdysone pulses, possibly as a repressor of transcription of target genes. Several interacting partners, for example USP, spire, and cut up were identified in a yeast two-hybrid screen. The spatio-temporal expression profiles of dEset and its potential partners suggest that they may act together or even in a larger complex.
