551-0320-00L	Cellular Biochemistry (Part II)	W	3 KP	2V	Y. Barral, R. Kroschewski, A. E. Smith
Kurzbeschreibung	This course will focus on molecular mechanisms and concepts underlying cellular biochemistry, providing advanced insights into the structural and functional details of individual cell components, and the complex regulation of their interactions. Particular emphasis will be on the spatial and temporal integration of different molecules and signaling pathways into global cellular processes.
Lernziel	The full-year course (551-0319-00 & 551-0320-00) focuses on the molecular mechanisms and concepts underlying the biochemistry of cellular physiology, investigating how these processes are integrated to carry out highly coordinated cellular functions. The molecular characterization of complex cellular functions requires a combination of approaches such as biochemistry, but also cell biology and genetics. This course is therefore the occasion to discuss these techniques and their integration in modern cellular biochemistry. The students will be able to describe the structural and functional details of individual cell components, and the spatial and temporal regulation of their interactions. In particular, they will learn to explain how different molecules and signaling pathways can be integrated during complex and highly dynamic cellular processes such as intracellular transport, cytoskeletal rearrangements, cell motility, and cell division. In addition, they will be able to illustrate the relevance of particular signaling pathways for cellular pathologies such as cancer or during cellular infection.
Inhalt	Spatial and temporal integration of different molecules and signaling pathways into global cellular processes, such as cell division, cell infection and cell motility. Emphasis is also put on the understanding of pathologies associated with defective cell physiology, such as cancer or during cellular infection.

Ban, D. Böhringer, M. A. Leibundgut, T. Lenarcic
Kurzbeschreibung	Many viruses have evolved specialized mechanisms to hijack the host gene expression machinery and employ cellular resources to regulate viral life cycle. They accomplish this through producing non-structural proteins that can, among other things, inhibit host protein synthesis. Participants of this course will visualize ribosomes in complex with a non-structural viral protein at high resolution.
Lernziel	The goal of the course is to acquire the most important techniques and methods for the purification and structural characterisation of macromolecular complexes by transmission electron microscopy. The emphasis of the course is on the special practical requirements for the application of these techniques on macromolecular structures in the MDa range.
Inhalt	Protein synthesis is a very energy intensive process that can consume over half the total metabolism of a cell. In eukaryotes, translation is therefore tightly regulated at the stage of initiation. Regulatory processes are much more complex at this step than in prokaryotes and a large number of RNA modification processes and translation initiation factors are required to ensure faithful initiation, elongation and termination of translation. However, several viruses may interfere with host translation by affecting the initiation step or by modifying the activity of key initiation factors to ensure an efficient translation of viral mRNA. Amongst such viruses is also SARS-CoV-2, which infects a large variety of vertebrate species. On entering host cells, the viral genomic RNA is translated by the cellular protein synthesis machinery to produce a set of non-structural proteins, which by inhibiting host translation render cell conditions favorable for viral production. Within the Ban lab, we have studied, and continue to investigate, medically relevant viral proteins. This course will involve producing and attempting to determine the structure of a non-structural viral protein in a ribosome-bound form. A variety of purification techniques, including affinity chromatography and ultracentrifugation, will be used during the purification of macromolecular complexes. Purified assemblies will be then investigated functionally. Students will then characterise their samples structurally through transmission electron cryo-microscopy (cryo-EM), including sample preparation, microscopy, data evaluation and the calculation of densities. Finally, students will learn how to build and refine molecular models into parts of the calculated cryo-EM density. The participants will be working on a closed project related to current research within the laboratory and throughout the course the practical work will be accompanied by brief theoretical introductions. The principal aim of the course is to strengthen the skills required to independently conduct meaningful biophysical and biochemical experiments and to provide an early introduction into the structural characterisation of cellular macromolecular assemblies.
Skript	A script will be distributed at the beginning of the course that will cover the experiments to be performed, provide references to the relevant literature and suggest points for further consideration for interested students.

Kurzbeschreibung	In this course you will learn to measure, integrate, analyze and validate the cellular surfaceome as a complex information gateway connecting the intracellular to the extracellular interactome. You will apply next generation technologies at the interface of biology, chemistry, medicine and bioinformatics to establish the surfaceome proteotype and its signaling interaction networks.
Lernziel	"If a cell surface molecule such as the B cell receptor would have the size of a human being, then the cell surface of a B cell would have roughly the size of three times NYC Central Park." How many people/proteins/proteoforms reside in this space ("Surfaceome")? Similar to humans, proteins don't act alone. Function is encoded in dynamic protein-protein interactions. How are these proteoforms organized in signaling islands/networks in order to fulfill specific cellular functions ("Interactome")? What are the ligands interacting with the surfaceome to communicate information from other cells & tissues in the body? What goes wrong in these signaling islands if we get sick? In this course you will learn to measure, integrate, analyze and validate the cellular surfaceome and its signaling islands as a complex information gateway connecting the intracellular to the extracellular interactome. You will apply next generation technologies at the interface of biology, chemistry, medicine and bioinformatics to generate unprecedented data to establish the surfaceome proteotype and its signaling interaction networks. This digital proteotype data layer provides the basis for generating qualitative and quantitative surfaceome models explaining how molecular nanoscale organization influences cellular signaling and biological function.
Inhalt	"If a cell surface molecule such as the B cell receptor would have the size of a human being, then the cell surface of a B cell would have roughly the size of three times NYC Central Park." How many people/proteins/proteoforms reside in this space ("Surfaceome")? Similar to humans, proteins don't act alone. Function is encoded in dynamic protein-protein interactions. How are these proteoforms organized in signaling islands/networks in order to fulfill specific cellular functions ("Interactome")? What are the ligands interacting with the surfaceome to communicate information from other cells & tissues in the body? What goes wrong in these signaling islands if we get sick?
