Signal relay in eukaryotes enables proper response to chemical or physical signals received by the cell. We now understand how many of the canonical components of signaling pathways exert their functions, including the mode of activation of many kinases and the relationships among receptors, scaffolds and downstream effectors. This understanding has been key to the development of therapeutics targeting signaling components. Yet, from receptors to enzymes such as kinases, phosphatases, ubiquitin ligases and deubiquitinases, the signaling machinery still holds many mysteries. 

In this session, we will focus on atypical signaling mechanisms, from the discovery of new catalysis within the kinome superfamily and noncanonical ubiquitination to the role of metals such as copper in signaling. We also discuss the emergence of pseudoenzymes: These allosteric signaling scaffolds are defined by their structural and sequence homology to canonical enzymes such as kinases and phosphatases, but they lack catalytic activity and remain relatively unexplored biologically and as potential drug targets. 

We also will discuss how improvements in phosphoproteomics, genetic screens, and affinity and proximity proteomics permit us to globally assess specific aspects of signal transduction and shine new lights on poorly characterized enzymes, scaffolds and substrates.

Keywords: signal transduction, phosphorylation, ubiquitination, post-translational modification, pseudoenzymes, mass spectrometry, CRISPR screens, structural biology, interaction mapping 

Who should attend: everyone who likes taking the road less traveled and those interested in good detective stories
