Our main research objective is to resolve the long-standing question: How do cells direct their proteome to fold to their native, functional state and avoid misfolding diseases. We are exploring the mechanisms guiding the folding and assembly of newly synthesized proteins into multi-molecular complexes as well as the mechanisms for degradation of “lonely” subunits. We are studying the role of the ribosome as a platform for coordinating complex assembly during synthesis, by advanced techniques combining biochemistry and deep sequencing such as selective ribosome profiling as well as super-resolution microscopy. We are also developing tools for studying single-molecule mRNA-protein interactions, in vivo.

Lab Manager & Research associate

Hagit Bar-Yosef, Ph.D

Picture of Hagit Bar-Yosef, Ph.D

BSc in molecular biology at the Department of Life Sciences, Bar-Ilan University, Israel. Master’s degree at Shimon Pollack`s lab, at the Department of Immunology in the Faculty of Medicine at the Technion-Israel Institute of Technology “Flagellin activation of Toll-Like Receptor 5 directs human monocytes into distinct differentiation towards dendritic cells”. Phd in Daniel Kornitze`s lab at the Department of Molecular Microbiology in the Faculty of Medicine at the Technion “Genetic and pharmacological suppression of fungalmorphogenesis”. In her work on Candida albicans, she showed that endocytosis is both essential and highly regulated in hyphal morphogenesis. Since 2017 she is working at the Biology Faculty, Technion. She first worked as head of student labs for bachelor’s studies at the faculty. In October 2019 she joined the lab and is working on co-translational protein folding.
