TranscriptomicsQuantitative modeling of transcription factor binding specificities using DNA shape
Accurate predictions of the DNA binding specificities of transcription factors (TFs) are necessary for understanding gene regulatory mechanisms. Traditionally, predictive models are built based on nucleotide sequence features. Here, we employed three- dimensional DNA shape information obtained on a ...

MetabolomicsThe Bardet-Biedl protein Bbs1 controls photoreceptor outer segment protein and lipid composition

Summary

Primary cilia are key sensory organelles whose dysfunction leads to ciliopathy disorders such as Bardet-Biedl syndrome (BBS). Retinal degeneration is common in ciliopathies, since the outer segments (OSs) of photoreceptors are highly specialized primary cilia. BBS...

ProteomicsProteome analysis of i-motif DNA binding proteins
Non-canonical DNA structures such as G-quadruplex (G4) and i-motif (iM) are formed at the guanine- and cytosine-rich sequences, respectively, and prohibit DNA replication and transcription. The formation and resolution of these non-canonical structures are therefore required to be dynamically regula...

ProteomicsDNA binding reorganizes the intrinsically disordered C-terminal region of PSC in Drosophila PRC1
Polycomb Group (PcG) proteins regulate gene expression by modifying chromatin. A key PcG complex, PRC1, has two activities: a ubiquitin ligase activity for histone H2A, and a chromatin compacting/nucleosome bridging activity that can inhibit transcription and chromatin remodeling. In Drosophila, the...

TranscriptomicsVariation in homeodomain DNA-binding revealed by high-resolution analysis of sequence preferences
Most homeodomains are unique within a genome, yet many are highly conserved across vast evolutionary distances, implying strong selection on their precise DNA-binding specificities. We determined the binding preferences of the majority (168) of mouse homeodomains to all possible 8-base sequences, re...

GenomicsMultiplexed identification of the genomic targets of DNA-binding proteins
Transcription factors direct gene expression, and so there is much interest in mapping their genome-wide binding locations. M-BM- Current methods do not allow for the multiplexed analysis of TF binding, and this limits their throughput. We describe a novel method for determining the genomic target g...

MetabolomicsATAD3A has a scaffolding role regulating mitochondria inner membrane structure and protein assembly

The ATPase Family AAA Domain Containing 3A (ATAD3A), is a mitochondrial inner membrane protein conserved in metazoans. ATAD3A has been associated with several mitochondrial functions, including nucleoid organization, cholesterol metabolism, and mitochondrial translation. To address its primary ro...

MetabolomicsBacteria encode their own post-mortem protein catabolism to enable nutrient recycling
For many organisms, death is a tangible, visible event. In bacteria, death can be a natural or an induced process 1. Death permits genes conferring a survival advantage to be selected in a bacterial population. Furthermore, biomolecule recycling from dead bacteria is crucial under nutrient limitatio...

ProteomicsGlobal profiling of protein-DNA and protein-nucleosome binding affinities using quantitative mass spectrometry
Interaction proteomics studies have provided fundamental insights into multimeric biomolecular assemblies and cell-scale molecular networks. Significant recent developments in mass spectrometry-based interaction proteomics have been fueled by rapid advances in label-free, isotopic, and isobaric quan...

Transcriptomics"Calling Cards" for DNA-binding proteins in mammalian cells
The ability to chronicle transcription factor binding events throughout the development of an organism would facilitate mapping of transcriptional networks that control cell fate decisions. We describe a method for permanently recording protein-DNA interactions in mammalian cells. We endow transcri...
