Monitoring Conformational Changes in Channel Proteins: A Novel Approach for Rapid Screening of Ion Channel Hits

Challenge: Ion channels are involved in numerous physiological functions, and as drug targets have been implicated in a wide range of pathological conditions. However, despite considerable effort, channel-targeted drug discovery has been hampered by the absence of adequate tools to functionally screen molecules that can modulate channel activity. Solution: The researchers have developed an innovative…

Acting on membrane protein-protein interactions: Mammalian Membrane Two Hybrid (MaMTH) as an Innovative Technology for Drug Discovery Against Protein- Protein Interactions

Challenge: Membrane proteins, representing approximately one-third of all proteins in a cell, interact with each other and are responsible for a variety of processes, making them attractive therapeutic targets for many diseases such as hypertension, diabetes, neurological disorders and various cancers. In fact, membrane proteins represent 60% of all clinical drug targets, however, they are…

Novel Methods to Evaluate Cardiac Activity of Pharmaceuticals: Identifying New Therapies and Predicting Cardiac Toxicity

Challenge: Current therapies for heart failure primarily relieve symptoms, but most fail to correct organ dysfunction. New therapies, to target and improve cardiomyocyte function, are challenging to develop because of the complex functions of the heart muscle and the difficulty in modeling heart cell behavior. The same problems underlie the difficulty in assessing the cardiotoxic…

FlAsH-Walk Mapping: An Innovative Step-by-Step Approach to G Protein-Coupled Receptor Conformation Cartography

Challenge: G protein-coupled receptors (GPCRs) are the largest target class for approved drugs. Identification of new drug candidates has relied exclusively on high-throughput assays which track binding properties and are limited to a restricted number of signaling pathways. GPCRs are highly dynamic proteins that undergo numerous conformational changes upon receptor association with ligands and related…

A 150-plex affinity proteomics platform for high throughput and high content phenotypic cell screening

Challenge: Proteins are the main effectors of cell activity and cardinal indicators of cell phenotype and response to stimuli such as drugs.  Whereas sequencing technologies currently allow for broad and efficient genomic and transcriptomic profiling, multiplexed protein detection technologies are either prohibitively slow and expensive, limited in scope due to reagent cross-reactivity, or both.  Critically,…
