The double helix is not the only structure formed by DNA and RNA. Guanine-rich DNA and RNA sequences can fold into quadruple-helix structures called G-quadruplexes. Recently, researchers visualized the unfolding of a G-quadruplex by a protein called DHX36, gaining valuable insight into a potential target for drug development. Read more »
Structures Reveal New Target for Malaria Vaccine
Researchers isolated human-derived antibodies that protect against malaria, and protein-structure studies revealed the antibodies’ site of attack. The discovery paves the way for the development of a more effective and practical human vaccine for malaria, which is responsible for half a million deaths every year. Read more »
Structure-based Design of Pyridone–Aminal eFT508 Targeting Dysregulated Translation by Selective Mitogen-activated Protein Kinase Interacting Kinases 1 and 2 (MNK1/2) Inhibition
Dysregulated translation drives key hallmarks of cancer and is controlled by Phase 2 candidate eFT508 binding to the MNK protein, exploiting stereoelectronic interactions, critical to the compound’s selectivity and potency. Read more »
NIH Grant Will Enhance Structural Biology Research Experience for ALS Users
A recently awarded National Institutes of Health (NIH) grant will help integrate existing structural biology resources at the ALS to better serve users. The funds will help establish a centralized collaborative mechanism, called ALS-ENABLE, that will guide users through the most appropriate routes for answering their biological questions. Read more »
Improving Meningococcal Vaccines
Scientists have found a way to improve the stability of an essential antigenic protein to develop vaccines with higher efficacy for prevention of bacterial meningitis. Read more »
A New Pathway for Radionuclide Uptake
Scientists have reported a major advance in understanding the biological chemistry of radioactive metals, opening up new avenues of research into strategies for remedial action in the event of possible human exposure to nuclear contaminants. Read more »
Validating Computer-Designed Proteins for Vaccines
Computationally designed proteins that accurately mimic key viral structures can help produce better vaccines. The resulting protein structures, validated at the ALS, encourage the further development of this strategy for a variety of vaccine targets, including HIV and influenza. Read more »
