1. Function via structure in vivo and in modeling
Abstract : Knowledge of biomolecules three-dimensional structure has provided a detailed understanding of their function. In recent years the number of new protein sequences has far exceeded the number of protein experimental structure determinations. READ MORE

2. The use of evolutionary information in protein alignments and homology identification
Abstract : For the vast majority of proteins no experimental information about the three-dimensional structure is known, but only its sequence. Therefore, the easiest way to obtain some understanding of the structure and function of these proteins is by relating them to well studied proteins. This can be done by searching for homologous proteins. READ MORE

3. Functional analysis of ligand recognition by the glucocorticoid receptor
Abstract : The glucocorticoid receptor (GR) is a ligand-inducible transcription factor that belongs to the superfamily of nuclear hormone receptors. It contains three structural and functional domains. READ MORE

4. Molecular basis for enhanced T-cell recognition and cross-reactivity
Abstract : T cells of the adaptive immune system recognize and kill infected cells by interacting with pathogenic peptides displayed on major histocompatibility complexes (MHC) through its T-cell receptor (TCR). TCR interactions with peptide/MHC complexes occur throughout the lifespan of T cells, from development to activation, with the origin of the peptide varying between self and foreign. READ MORE

5. Computational Modeling of the AT2 Receptor and AT2 Receptor Ligands : Investigating Ligand Binding, Structure–Activity Relationships, and Receptor-Bound Models
Abstract : Rational conversion of biologically active peptides to nonpeptide compounds with retained activity is an appealing approach in drug development. One important objective of the work presented in this thesis was to use computational modeling to aid in such a conversion of the peptide angiotensin II (Ang II, Asp-Arg-Val-Tyr-Ile-His-Pro-Phe).
