英文摘要
The overall rationale of the research in our laboratory is to
discover structural, dynamic and electronic determinants of biological
processes that underlie physiological functions, using methods of
theoretical and computational biophysics. We seek a molecular level,
mechanistic understanding of structure-function relationships anchored
in experimental information about structures and properties of
cellular components and physiological mechanisms. Our approaches use
well-defined algorithms based on the fundamental laws of classical and
quantum physics; they include computer assisted modeling of molecular
structure and properties and computational simulations of molecular
mechanisms. The theoretical studies are designed to complement
experimentation in providing mechanistic insights about systems of
ever increasing size and complexity, and to guide pointed experimental
exploration of cellular processes and functions in numerous
collaborative studies. To facilitate the interaction between the
theoretical and experimental studies, the projects described below are
carried out in close collaboration with experimental groups. The
theoretical methods we use are also being expanded, refined and tested
in the study of biomolecular systems. The goals of these
methodological developments are to extend the scope of problems that
can be studied by computational approaches, deepen the insights that
can be obtained from the computations with novel and sophisticated
methods of analysis, and allow the fast calculation of properties that
are of direct experimental relevance. As documented in our
publications, our work addresses major areas of current research. A
unifying theme in our studies of diverse biological processes is to
achieve a molecular understanding of mechanisms triggered by molecular
recognition and leading to signal transduction. Currently, we study
structural specificity and dynamics in three main areas in which such
processes determine essential physiological mechanisms as follows: i)
The determinants of specificity in mechanisms of cellular signaling
through ligand recognition and receptor response; ii) the decoding and
processing of Ca2+ signals through the EF-hand Ca-binding proteins;
and iii) the specificity and functional trigger produced by protein
binding to DNA. A fourth area comprises the formulation and
development of an implicit solvent model for fast computer simulations
of biological systems.
