Direct and selective pharmacological disruption of the YAP-TEAD interface by IAG933 inhibits Hippo-dependent and RAS-MAPK-altered cancers.

The YAP-TEAD protein-protein interaction mediates YAP oncogenic functions downstream of the Hippo pathway. To date, available YAP-TEAD pharmacologic agents bind into the lipid pocket of TEAD, targeting the interaction indirectly via allosteric changes. However, the consequences of a direct pharmacological disruption of the interface between YAP and TEADs remain largely unexplored.

Rapid inactivation of the yeast Sec complex selectively blocks transport of post-translationally translocated proteins.

The yeast endoplasmic reticulum has three distinct protein translocation channels. The heterotrimeric Sec61 and Ssh1 complexes, which bind translating ribosomes, mediate cotranslational translocation of proteins targeted to the endoplasmic reticulum by the signal recognition particle (SRP) and SRP receptor targeting pathway, whereas the heptameric Sec complex has been proposed to mediate ribosome-independent post-translational translocation of proteins with less hydrophobic signal sequences that escape recognition by the SRP. However, multiple reports have proposed that the Sec complex may function cotranslationally and be involved in translocation or integration of SRP-dependent protein translocation substrates.

NACHO Engages N-Glycosylation ER Chaperone Pathways for α7 Nicotinic Receptor Assembly.

The α7 nicotinic acetylcholine receptor participates in diverse aspects of brain physiology and disease. Neurons tightly control α7 assembly, which relies upon NACHO, an endoplasmic reticulum (ER)-localized integral membrane protein. By constructing α7 chimeras and mutants, we find that NACHO requires the α7 ectodomain to promote receptor assembly and surface trafficking.

Novel calixarene-based surfactant enables low dose split inactivated vaccine protection against influenza infection.

Influenza A viruses cause major morbidity and represent a severe global health problem. Current influenza vaccines are mainly egg-based products requiring the split of whole viruses using classical detergents such as Triton X-100, which implies certain limitations. Here, we report the use of the novel calixarene-based surfactant CALX133ACE as an alternative to classical detergents for influenza inactivated split vaccine preparation.
