    Selection of an artificial binding protein against the ectodomain of PTH1R Dissertation Zur Erlangung des akademischen Grades doctor rerum naturalium (Dr. rer. nat.) vorgelegt bei der Naturwissenschaftlichen Fakultät I Biowissenschaften der Martin-Luther-Universität Halle-Wittenberg von Qi Zhang geboren am 21.09.1983 in Shaanxi, China Gutachter /in 1. PD. Dr. Hauke Lilie 2. Prof. Dr. Jochen Balbach 3. Prof. Dr. Annette G. Beck-Sickinger Verteidigungsdatum: 14.03.2013 Zusammenfassung In den vergangenen Jahrzehnten fanden mehr als 30 Immunglobuline (IgGs) und deren Derivate Anwendung in der klinischen Praxis. Trotz des großen Erfolgs solcher Antikörper-basierter Medikamente traten auch einige Limitationen auf. Gerüstproteine stellen eine Alternative zu herkömmlichen Antikörpern dar. Sie weisen meist eine hohe thermodynamische Stabilität auf und bestehen aus einer einzelnen Polypeptidkette ohne Disulfidbrücken. Universelle Bindestellen können wie beim humanen Fibronectin III und bei Anticalinen in flexiblen Loop-Regionen erzeugt werden oder auf rigiden Sekundärstrukturelementen, wie im Fall der Affibodies, DARPine und Affiline. In der vorliegenden Arbeit wurde eine Protein-Bibliothek auf Basis des humanen γB-Kristallins, unter Randomisierung von 8 oberflächenexponierten Aminosäuren auf einem β-Faltblatt der N-terminalen Domäne des Proteins, hergestellt. Ein kürzlich entwickeltes Screening-System, das T7-basierte Phagen-Display, wurde zur Durchmusterung der Bibliothek auf potentielle Binder angewandt. Dabei erfolgt die Assemblierung der Protein-präsentierenden Phagenpartikel ohne einen Transportschritt über die Zellmembran hinweg bereits im Cytoplasma von E. coli. G-Protein gekoppelte Rezeptoren (GPCRs) bilden nur schwerlich für Strukturuntersuchungen geeignete, geordnete Kristallstrukturen aus. Kleine, gut lösliche Bindeproteine könnten sie in einer bestimmten Konformation fixieren und so den Anteil an hydrophilen Resten auf der Proteinoberfläche erhöhen.

  • Understanding Ubiquitin Recognition and Generating Affinity Reagents
    Ubiquitin Engineering: Understanding Ubiquitin Recognition and Generating Affinity Reagents by Isabel Leung A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Molecular Genetics University of Toronto © Copyright by Isabel Leung 2017 Abstract Ubiquitin Engineering: Understanding Ubiquitin Recognition and Generating Affinity Reagents Isabel Leung Doctor of Philosophy Department of Molecular Genetics University of Toronto 2016 Protein-protein interactions are necessary for virtually all biological processes. There have been tremendous efforts to document the diversity of molecular recognition, and to understand how molecular recognition occurs. The understanding of molecular interaction has also served as the foundation for designing novel protein interactions for use in therapeutics, diagnostics and basic sciences. An attractive system for studying protein-protein interactions is the ubiquitin (Ub) system. Ub is a protein modifier that is combinatorially ligated onto substrate proteins to influence substrate turnover and function. Ub uses a common surface to interact with more than 1000 proteins and plays pivotal roles in cell physiology. Despite the substantial structural information on Ub mediated interactions, there is no clear understanding of how individual Ub residues contribute to Ub’s broad scope of interactions. To address this question, I used affinity enhanced Ub variants (Ubvs) as proxies of native Ub in saturation scanning. Using saturation scanning, I studied the interactions between Ubvs and two Ub specific proteases (USP), USP2 and USP21, and elucidated a common functional epitope that is critical for USP recognition. The functional epitope recognizes USP residues that are conserved among the human USP family, suggesting it may make functional contributions in many other USP interactions.
