Current Research

DNA structural codes in genomes. The development of diseases caused by mutations in the genome is not only explained by changes in protein-coding regions leading to dysfunctional proteins. Mutations affecting DNA structure and genome organization involving physiological and pathological processes are likewise linked to human diseases. The three-dimensional molecular structure of DNA, specifically the shape of the backbone and grooves of genomic DNA, can be dramatically affected by nucleotide changes, which can cause differences in protein-binding affinity and phenotype. Thus, knowing the DNA structure along the DNA of the genome is important for a detailed understanding of the DNA function.  Accordingly, the mutability of a gene or genomic region may also be influenced indirectly by a variety of nearby non-canonical secondary DNA structures whose formation is facilitated by the underlying DNA sequence.  These structures may be involved in mutational mechanisms underlying human diseases. Consequently, the effect of a base pair mutation cannot be predicted solely by identifying the base pair because a given base pair changes may affect or develop a secondary DNA structure several base pairs away from the mutation through allosteric transformation in the DNA.

Potential projects for master and PhD students:

  • Identify new DNA structural elements in genomes, which may be linked to function and diseases.
  • Study allosteric effect on DNA structure and function as a consequence of base pair modifications.
  • Develop and use bioinformatics tools for genomic analysis of mutational effects on DNA structure and function.
