Learning outcomes The main objective is to study the structural and conformational characteristics of proteins and their biological function. It is also intended to relate conformational changes with certain diseases through examples of proteins that perform diverse biological functions.
At the end of this course students should be able to:
-Identify and describe the fundamental principles that define the structure and conformation of proteins and the mechanisms that control in vitro and in vivo protein folding;
-Describe the relation between the onset of neurodegenerative diseases with protein conformational changes;
-Explain the cellular strategies for protein quality control;
-Apply different methods for crystalization and analysis of proteins (X-ray diffraction, circular dichroism, IR spectroscopy, fluorescence, nuclear magnetic resonance, surface plasmon resonance);
-Demonstrate capacity for critical analysis and presentation of scientific papers.
Syllabus 1- Visualization and computational design of organic molecules. Analysis of molecular interactions between protein receptors and ligands by Docking.
2-Methods for structure determination of proteins: X-rays diffraction crystallography and nuclear magnetic resonance (NMR). Circular Dichroism (CD). Determination of protein-ligand interactions by Surface Plasmon Resonance. IR spectroscopy, fluorescence.
3-Membrane proteins. Expression, purification and crystallization methods
4-Cellular strategies for protein quality control
5-Protein Folding. Conformational stability. In vitro and in vivo folding mechanisms. Misfolding and disease: molecular mechanisms of formation of protein aggregates in disease.
6-Experimental work:
-Crystallization of lysozyme.
-CD of proteins.
-Determination of structure of an aminoacid by NMR.
- Fluorescence analysis of proteins
-Structural Analysis of Protein-ligands Interactions by SPR.
