SUMOylation of Bonus, the Drosophila homolog of Transcription Intermediary Factor 1, safeguards germline identity by recruiting repressive chromatin complexes to silence tissue-specific genes [RNA-seq-MT-Gal4]

Project description:The conserved family of Transcription Intermediary Factors (TIF1) proteins consists of key transcriptional regulators that control transcription of target genes by modulating chromatin state. Unlike mammals that have four TIF1 members, Drosophila only encodes one member of the family, Bonus. Bonus has been implicated in embryonic development and organogenesis and shown to regulate several signaling pathways, however, its targets and mechanism of action remained poorly understood. We found that knockdown of Bonus in early oogenesis results in severe defects in ovarian development and in ectopic expression of genes that are normally repressed in the germline, demonstrating its essential function in the ovary. Recruitment of Bonus to chromatin leads to silencing associated with accumulation of the repressive H3K9me3 mark. We show that Bonus associates with the histone methyltransferase SetDB1 and the chromatin remodeler NuRD and depletion of either component releases Bonus-induced repression. We further established that Bonus is SUMOylated at a single site at its N-terminus that is conserved among insects and this modification is indispensable for Bonus’s repressive activity. SUMOylation influences Bonus’s subnuclear localization, its association with chromatin and interaction with SetDB1. Finally, we showed that Bonus SUMOylation is mediated by the SUMO E3-ligase Su(var)2-10, revealing that although SUMOylation of TIF1 proteins is conserved between insects and mammals, both the mechanism and specific site of modification is different in the two taxa. Together, our work identified Bonus as a regulator of tissue-specific gene expression and revealed the importance of SUMOylation as a regulator of complex formation in the context of transcriptional repression.

Yorkie and Bonus protein interactome-Hippo pathway and Bonus control developmental cell fate decisions in the Drosophila eye

Project description:To identify novel regulators of the Hippo pathway, we performed affinity purification-mass spectrometry (AP-MS) using Drosophila embryos overexpressing Yki-EGFP with a ubiquitous driver da-GAL4, as well as cultured S2 cells expressing Yki-SBP. We identified the core Hippo pathway components, multiple Hippo pathway regulators and functional groups, and several putative Yki interactors including Bonus (Bon). To identify additional cofactors that are recruited by Bon, we performed AP-MS using Bon-SBP expressed in Drosophila S2 cells. Further genetic tests revealed the involvement of Bon interactors, HDAC1, Su(var)2-10, and Hrb27C, in the Drosophila eye specification that is regulated by the Yki-Bon complex.
