Wubing Zhang

Machine learning modeling of protein-intrinsic features predicts tractable targets of protein degraders


Markus Queisser

High Throughput Approaches in Targeted Protein Degradation and PROTAC Synthesis


Markus got interested in protein degradation during his Master’s in Biochemistry at Free University Berlin, where he worked on understanding proteasome function. He further gained broad knowledge in respiratory diseases, inflammation and oncology while pursuing a Ph.D. in Biomedical Sciences at an international graduate programme at UGLC in Germany and Albert-Einstein College of Medicine. Markus then moved on to postdoctoral training at Northwestern University, where in collaboration with Noble Laureate Aaron Ciechanover, he characterised the regulation of ubiquitin ligase HOIL as a key mechanism of tumor adaptation to hypoxia. Prior to joining GSK, he specialized in ubiquitin-ligase recruitment at the Ludwig Institute for Cancer Research. Currently, Markus is a GSK Fellow and Scientific Director in the Protein Degradation Group at GSK, leading the technology team and multiple collaborations with biotechs and academia.

Chao Sun - Max Planck Institute for Brain Research

Subcellular Stoichiometry of Neuronal Proteasome Assembly

Dr. Chao Sun is an EMBO & HFSP postdoctoral fellow in Prof. Erin M. Schuman's lab at Max Planck Institute for Brain Research, Germany. His current research uses quantitative, multiplexed super-resolution microscopy to investigate the molecular resource supply for the vast population of synapses associated with a single neuron. He obtained his PhD with Prof. William R. Dichtel at Cornell University, US (now at Northwestern University, US), where he designed and manipulated molecular interactions to interface two-dimensional materials and molecular analogues for creating smart nano- materials and devices. His future research continues to focus on understanding and creating molecular systems that can 'think'.

Nan Bai - Amgen

Modeling CRL4A ligase complex to predict target protein ubiquitination induced by CRBN-recruiting PROTACs

I completed my PhD in Dr. John Karanicolas’ lab at Fox Chase Cancer Center (2012-2019), and my dissertation is about small molecule drug design. In my PhD lab, we use computational tools to study drug/target interactions and to further rationally design more effective drugs. During my PhD journey, one of my projects was focused on modeling PROTAC-mediated ternary complex formation. I am really attracted by this PROTAC concept and would like to explore more about this class of promising therapeutics. In 2020, I was very fortunate to join the Pharmacokinetics and Drug Metabolism (PKDM) group of Amgen as a postdoc and started to work on more PROTAC related projects. In my current work, we propose a structure-based computational approach to predict CRBN-based PROTAC induced target protein ubiquitination by integrating ternary complex and CRL4A ligase complex structural information.

Daniel Zaidman - University of Cambridge

PRosettaC: Rosetta Based Modeling of PROTAC Mediated Ternary Complexes

Daniel Zaidman started his studies in Tel-Aviv University, Israel, and finished a dual B.Sc. in mathematics and computer science. He then proceeded to do his master degree in bioinformatics in the lab of Prof. Haim Wolfson in Tel-Aviv University. In his masters he worked on designing inhibitory peptides for protein-protein interactions. He did his PhD in the lab of Dr. Nir London in the Weizmann Institute, where he worked on computational protocols for two uprising domains in drug discovery, namely, covalent inhibitors (such as Ibrutinib, Afatinib, etc.), and protein degraders (PROTACs). For both of these fields, he developed elegant protocols, combining novel ideas, end-to-end implementation and interactive web-servers to use the algorithms he developed. Currently he is pursuing his postdoc in the University of Cambridge, in the lab of Dr. Gonçalo Bernardes. Outside the university, his interests include foreign languages and Buddhist meditation.

Xiuxiu Lu - NCI/NIH

Structure-guided hRpn13-targeting bifunctional molecules as chemical probes of hRpn13 dysfunction
Dr. Xiuxiu Lu received her Ph. D. from the Shanghai Institute of Organic Chemistry, CAS for her structural studies that yielded a new model of DNA cytidine deaminase APOBEC3G with HIV single-stranded DNA in an active orientation. In 2014, Dr. Lu joined NCI/NIH as a postdoctoral fellow and was promoted to a research fellow in 2019. Dr. Lu solved the structure of ubiquitin receptor hRpn13 with its docking site at the proteasome by NMR and applied biochemical assays to provide novel insights into the potential of hRpn13 and its associated deubiquitinating enzyme Uch37 as anticancer targets. Dr. Lu has identified a chemical scaffold to target hRpn13 and found the lead compound XL5 to reduce cellular viability in cancer cell lines. By solving the structure of hRpn13 with XL5, Dr. Lu expanded the small molecule to include Proteolysis Targeting Chimeras (PROTAC) technology, yielding bifunctional molecules with greater efficacy in cellular assays.

Agatheeswaran Subramaniam - Lund University

Agathees is interested in developing targeted therapies for selectively eliminating cancer propagating cells. During his postdoctoral research, he unraveled the targeted protein degradation mechanism of a small molecule UM171 and actively developing a research program in this field.

Hijacking The Ubiquitin System for Protein Degradation Therapeutics

Host: Katherine Donovan


Eric Fischer, PhD, is Independent Investigator at Dana-Farber Cancer Institute and Associate Professor of Biological Chemistry and Molecular Pharmacology at Harvard Medical School. He is also the Director of the DFCI/Deerfield Center for Protein Degradation.

Dr. Fischer’s research focuses on understanding the molecular architecture, function, and regulation of complex cellular signaling machines and their involvement in cellular processes. His lab leverages this knowledge to develop new strategies for small-molecule-mediated modulation. Using biochemistry, chemical biology, and cell biology methods, his lab has contributed to the understanding of the efficacy and adverse activity of thalidomide and related drugs. Beyond defining the mechanism of action for this transformative cancer drug and solving a decade-old mystery of pharmaceutical sciences, this work inspired numerous projects that intend to utilize similar principles to redirect ligase activity to new targets. This represents a new therapeutic modality often referred to as targeted protein degradation. Dr. Fischer’s lab helped to establish this approach and has defined many of the underlying principles for small molecule degraders. Dr. Fischer’s work has been recognized with awards including, the Damon Runyon Cancer Research Foundation’s 2017 Damon Runyon-Rachleff Innovation Award, and the Mark Foundation’s 2018 Emerging Leaders Award. Dr. Fischer is a co-founder of Civetta Therapeutics, Neomorph, Inc and Jengu Therapeutics.

Dr. Fischer completed his undergraduate training at the Universities of Hamburg (Germany) and Basel (Switzerland) and completed doctoral training at the Friedrich Miescher Institute for Biomedical Research, also in Basel. Dr. Fischer joined the Dana-Farber faculty in 2015.
