Defining the sequence-recognition profile of DNA-binding molecules.
Determining the sequence-recognition properties of DNA-binding proteins and small molecules remains a major challenge. To address this need, we have developed a high-throughput approach that provides a comprehensive profile of the binding properties of DNA-binding molecules. The approach is based on displaying every permutation of a duplex DNA sequence (up to 10 positional variants) on a microf...
متن کاملDesign of sequence-specific DNA-binding molecules.
Base sequence information can be stored in the local structure of right-handed double-helical DNA (B-DNA). The question arises as to whether a set of rules for the three-dimensional readout of the B-DNA helix can be developed. This would allow the design of synthetic molecules that bind DNA of any specific sequence and site size. There are four stages of development for each new synthetic seque...
متن کاملA MODEL FOR THE BASIC HELIX- LOOPHELIX MOTIF AND ITS SEQUENCE SPECIFIC RECOGNITION OF DNA
A three dimensional model of the basic Helix-Loop-Helix motif and its sequence specific recognition of DNA is described. The basic-helix I is modeled as a continuous ?-helix because no ?-helix breaking residue is found between the basic region and the first helix. When the basic region of the two peptide monomers are aligned in the successive major groove of the cognate DNA, the hydrophobi...
متن کاملDefining the pathogenicity of DNA sequence variation.
Mendelian Disorders For many cardiac or vascular conditions in which the initial presentation may be fatal, a strong genotype–phenotype correlation is of fundamental importance if genetic diagnosis or prognostication is ever to be useful. Even in classic monogenic disorders, in which large effect sizes are observed, genetic prediction is often confounded by reduced penetrance, wide variation in...
متن کاملDesign of Sequence-Specific DNA Binding Molecules for DNA Methyltransferase Inhibition
The CpG dyad, an important genomic feature in DNA methylation and transcriptional regulation, is an attractive target for small molecules. To assess the utility of minor groove binding oligomers for CpG recognition, we screened a small library of hairpin pyrrole-imidazole polyamides targeting the sequence 5'-CGCG-3' and assessed their sequence specificity using an unbiased next-generation seque...
