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...

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...

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...

GenomicsCondensin association with chromosomes depends on a DNA binding domain formed by its HEAT-repeat subunits
Condensin protein complexes play central roles in the three-dimensional organization of chromosomes during mitotic and meiotic cell divisions. How condensin interacts with its chromatin substrates to promote sister chromatid decatenation and segregation is largely unknown. Previous work suggested th...

ProteomicsA novel domain essential for interdomain cooperativity in binding of a Rep protein to DNA.
A very important feature of replication initiation proteins is the ability to bind to DNA via a characteristic domain. Usually, one or two DNA-binding domains can be distinguished within each initiator. In this work, we specified a new family of replication initiation proteins (the TrfA-like protein...

GenomicsGenome-wide binding profiles of KLF3 and KLF3 mutants in MEF cells
Transcription factors are often regarded as being comprised of a DNA-binding domain and a functional domain. The two domains are considered separable and autonomous, with the DNA-binding domain directing the factor to its target genes and the functional domain imparting transcriptional regulation. W...

GenomicsHT-SELEX of wild-type and mutated versions of recombinant DNA binding domain of SALL4
To investigate the differences in DNA binding specificity of wild-type SALL4 C2H2 zinc finger cluster 4 (ZFC4) and disease causing mutations in SALL4 ZFC4, we performed SELEX coupled with high-throughput sequencing (HT-SELEX) using the purified wild-type SALL4 ZFC4 domain, mutated SALL4 ZFC4 (R900W)...

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...
