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...

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 ...

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...

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...

ProteomicsMudPIT analysis of proteins extracted from mouse KH2ES cell nuclei and enriched by binding to immobilized DNA fragments
Sample Preparation: To identify proteins that are recruited by Hoxb1 to two newly identified DNA motifs, namely Motif_2 and LONG2x, nuclear extracts from 24hrs Retinoic acid- and Doxycycline-induced KH2 cell line with inducible Hoxb1 were added to DNA fragments immobilized on magnetic beads. Five ex...

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...

ProteomicsNucleosome binding by the pioneer transcription factor OCT4
The nucleosome is a fundamental unit of chromatin in eukaryotes, and generally prevents the binding of transcription factors to genomic DNA. Pioneer transcription factors overcome the nucleosome barrier, and bind their target DNA sequences in chromatin. OCT4 is a representative pioneer transcription...
