Drosophila G9a is a nonessential gene.
Mammalian G9a is a euchromatic histone H3 lysine 9 (H3K9) methyltransferase essential for development. Here, we characterize the Drosophila homolog of G9a, dG9a. We generated a dG9a deletion allele by homologous recombination. Analysis of this allele revealed that, in contrast to recent findings, dG9a is not required for fly viability.
متن کاملThe Drosophila zeste locus is nonessential.
Diepoxybutane-induced mutations of the Drosophila zeste locus were generated in an effort to obtain a null allele. Of 33 mutations of this X-linked gene isolated, 16 were associated with multilocus deletions of zeste and adjacent complementation groups, while the remainder were defects restricted to zeste undetectable by Southern blot analysis. Two of these multilocus deletions (Df(1)zdeb3 and ...
متن کاملThe Drosophila melanogaster sir2+ gene is nonessential and has only minor effects on position-effect variegation.
Five Drosophila melanogaster genes belong to the highly conserved sir2 family, which encodes NAD(+)-dependent protein deacetylases. Of these five, dsir2(+) (CG5216) is most similar to the Saccharomyces cerevisiae SIR2 gene, which has profound effects on chromatin structure and life span. Four independent Drosophila strains were found with P-element insertions near the dsir2 transcriptional star...
متن کاملThe Drosophila G9a gene encodes a multi-catalytic histone methyltransferase required for normal development
Mammalian G9a is a histone H3 Lys-9 (H3-K9) methyltransferase localized in euchromatin and acts as a co-regulator for specific transcription factors. G9a is required for proper development in mammals as g9a-/g9a- mice show growth retardation and early lethality. Here we describe the cloning, the biochemical and genetical analyses of the Drosophila homolog dG9a. We show that dG9a shares the stru...
متن کاملBacillus subtilis ypgA gene is fni, a nonessential gene encoding type 2 isopentenyl diphosphate isomerase.
We previously identified the fni gene of Streptomyces sp. strain CL190 as type 2 isopentenyl diphosphate (IPP) isomerase, which needs both FMN and NADPH for enzyme activity. An fni gene homolog, ypgA, was detected in the database of the Bacillus subtilis genome. However, the ypgA product was about 140 amino acids shorter in the N-terminal than the Streptomyces fni gene product. A database searc...
