TranscriptomicsSMAUG is required for zygotic transcription during the maternal-zygotic transition MZT
Microarray analysis of zygotic gene expression in 2-to-3 hour wild-type (wt) and smg mutant embryos. Expression is relative to mature, stage 14 oocytes, which contain the full maternal pool of mRNA. Strictly maternal genes that are not transcribed at the MZT contribute approximately 80% of transc...

TranscriptomicsmiR-309-dependent unstable maternal mRNAs are stabilized in smaug mutants
The behavior of 410 miR-309-dependent maternal mRNAs (from Bushati et al., 2008) in embryos from wild type and smg-mutant females relative to wild-type stage 14 oocyte reference RNA. All are unstable in wild-type while almost 85% are stabilized in smg mutants mRNA was extracted from staged embryos a...

TranscriptomicsSMAUG Is a Major Regulator of Maternal mRNA Destabilization in Drosophila
In animals, egg activation triggers a cascade of posttranscriptional events that act on maternally synthesized RNAs. We show that, in Drosophila, the PAN GU (PNG) kinase sits near the top of this cascade, triggering translation of SMAUG (SMG), a multifunctional posttranscriptional regulator conserve...
