Research Description

Consider the incredible diversity of cells and tissues in our own bodies: an information transmitting nerve cell and a bacteria-hunting white blood cell look and act nothing alike, yet they are specified by the same genome. This feat – phenotypic diversity without genetic diversity – is accomplished by genes that turn on and off other genes in a so-called ‘regulatory network’. We seek to understand how are these regulatory networks are encoded in genome sequences. How is information in the genome converted into regulatory interactions between proteins? One of the important components of this ‘regulatory code’ has been discovered: ‘regulatory motifs’ in the sequences of DNA, RNA and proteins. One of the major aims of our research is to develop computational and statistical tools to identify these motifs. Just as differential gene activity can explain cellular and physiological diversity within a single organism (nerve cell vs. white blood cell with same genes), it has also been proposed as explanation for physiological and morphological differences between closely related organisms (chimpanzee vs. human with very similar genes). We seek to understand how regulatory networks are sculpted by evolution. Can genetic changes in regulatory interactions explain evolutionary changes in function and form? We focus on the evolution of regulatory motifs because, by mediating the regulatory interactions, they specify the connections in regulatory networks. Our goal is to translate the evolutionary differences in regulatory motifs to quantitative differences in regulatory networks, and ultimately, to their impact on organismal fitness.
