GenomicsLigand-dependent dynamics of retinoic acid receptor binding during early neurogenesis
Among its many roles in development, retinoic acid determines the anterior-posterior identity of differentiating motor neurons by activating Retinoic Acid Receptor (RAR)-mediated transcription. RAR is thought to bind the genome constitutively, and only induce transcription in the presence of the ret...

MetabolomicsAntioxidant Activity, Phytochemical Profiling by UPLC-QTOF-MS, and In Silico Targeting of the RNA-Binding Protein DRBD18 of Trypanosoma brucei by Bioactive Compounds from Tetradenia riparia and Tetracera poggei
Oxidative stress plays a key role in the pathogenesis of African trypanosomiasis, and plant-derived antioxidants represent a promising source of dual-action compounds capable of both scavenging reactive oxygen species and interfering with parasite survival. The present study investigates the antioxi...

ProteomicsLigand binding and conformational dynamics of the E. coli nicotinamide nucleotide transhydrogenase revealed by hydrogen/deuterium exchange mass spectrometry
Nicotinamide nucleotide transhydrogenases are integral membrane proteins that utilizes the proton motive force to reduce NADP+ to NADPH while converting NADH to NAD+. Atomic structures of various transhydrogenases in different ligand-bound states have become available, and it is clear that the molec...

GenomicsGenome-wide binding profiles of an artificial zinc finger protein with or without a KLF3 functional domain
Transcription factors are often regarded as having two distinct components: a DNA binding domain (DBD) to allow binding to the regulatory region of a target gene and a trans-acting functional domain (FD) to modulate gene expression. Recently, it is becoming clear that the DBDs of transcription facto...

ProteomicsThe multivalency of the glucocorticoid receptor ligand-binding domain explains its manifold physiological activities
The glucocorticoid receptor (GR) is a ubiquitously expressed transcription factor that controls metabolic and homeostatic processes essential for life. Although numerous crystal structures of the GR ligand-binding domain (GR-LBD) have been reported, the functional oligomeric state of the full-length...

TranscriptomicsAn Extended dsRBD with a Novel Zinc-Binding Motif Mediates Nuclear Retention of Fission Yeast Dicer
Dicer proteins function in RNA interference (RNAi) pathways by generating small RNAs (sRNAs). Here we report the solution structure of the C-terminal domain of Schizosaccharomyces pombe Dicer (Dcr1). The structure reveals an unusual double-stranded RNA binding domain (dsRBD) fold embedding a novel z...

ProteomicsMass spectrometry insights into a tandem ubiquitinâ??binding domain hybrid engineered for the selective recognition of unanchored polyubiquitin
Unanchored polyubiquitin chains are emerging as important regulators of cellular physiology with diverse roles paralleling those of substrate-conjugated polyubiquitin. However tools able to discriminate unanchored polyubiquitin chains of different isopeptide linkages have not been described. We desc...

GenomicsCTCF demarcates chromatin domains
Insulators are DNA elements, which prevent inappropriate interactions between the neighboring regions of the genome. They can be functionally classified as either enhancer blockers or domain barriers. CTCF (CCCTC binding factor) is the only known major insulator binding protein in the vertebrates a...

GenomicsThe SPOC domain is a phosphoserine binding module that bridges transcription machinery with co- and post-transcriptional regulators - ChIP-seq
The heptarepeats of the C-terminal domain of Pol II are extensively modified throughout the transcription cycle. The CTD coordinates RNA synthesis and processing by recruiting transcription regulation factors as well as RNA capping, splicing and 3’end processing factors. The SPOC domain of PHF3 was ...

ProteomicsStructure of the Homodimeric Androgen Receptor Ligand-Binding Domain
The androgen receptor (AR) plays a crucial role in normal physiology, development and metabolism as well as in the etiology and treatment of diverse pathologies such as androgen insensitivity syndromes (AIS), male infertility, and prostate cancer (PCa). Here, we show that dimerization of AR ligand-b...
